This method allows the calling session to set transaction hints for the package manager which can change as the transaction runs.
This method can be sent before the transaction has been run or whilst it is running. There is no limit to the number of times this method can be sent, although some backends may only use the values that were set before the transaction was started.
Each parameter value is optional.
|
The values as an array of strings, for example ['locale=en_GB.utf8','idle=true','interactive=false','cache-age=3600']. The following parameter values are understood: locale The locale code, for example en_GB. background If the method should be executed as a background task, valid values are true and false, and other values will result in an error. Background tasks are normally treated with a low priority than regular tasks, and normally only use idle CPU and network. interactive If the method can ask interactive questions whilst running, valid values are true and false, and other values will result in an error. cache-age This allows the frontend to set how fresh it needs the metadata used in the transaction. This allows fine control of the age of the returned results, but means the frontend probably has to query the updates check value and pass it this value for GetUpdates, and choose something sane otherwise. Most interactive clients will set this to intmaxdoc:tt> which means "never download new metadata, unless required to return results". Most transactions will not have this value set. Other values will cause a verbose warning in the daemon, but will not cause the method to fail. This will preserve forward and backwards compatibility for future API versions. |
This method allows the user to accept a end user licence agreement.
|
A valid EULA ID |
This method cancels a transaction that is already running
This method downloads packages into a temporary directory.
This method should emit one Files signal for each package that is downloaded, with the file list set as the name of the complete downloaded file and directory, so for example:
DownloadPackages('hal;0.1.2;i386;fedora','hal-info;2009-09-07;no-arch;updates') should send two signals, e.g. Files('hal;0.1.2;i386;fedora', '/tmp/hal-0.1.2.i386.rpm') and Files('hal-info;2009-09-07;no-arch;updates', '/tmp/hal-info-2009-09-07.noarch.rpm').
|
If the downloaded files should be stored in the system package cache rather than copied into a newly created directory. See the developer docs for more details on how this is supposed to work. |
|
An array of package IDs. |
This method return the collection categories
This method returns packages that this package depends on.
This method typically emits Progress, Status and Error and Package.
Package enumerated types should be available or installed.
|
A correct filter, e.g. none or installed;~devel |
|
An array of package IDs. |
|
Either true or false. If yes then the requirements should be returned for all packages returned. This means if gnome-power-manager depends on NetworkManager and NetworkManager depends on HAL, then GetDepends on gnome-power-manager should return both HAL and NetworkManager. |
This method should return all the details about a specific package_id.
This method typically emits Progress, Status and Error and Details.
|
An array of package IDs. |
This method should return the file list of the package_id.
This method typically emits Progress, Status and Error and Files.
|
An array of package IDs. |
This method allows a client to view details for old transactions.
|
The number of past transactions, or 0 for all known transactions. |
This method returns all the packages without a search term.
This method typically emits Progress, Error and Package.
Package enumerated types should be available or installed.
|
A correct filter, e.g. none or installed;~devel |
This method returns the list of repositories used in the system.
This method should emit RepoDetail.
|
A correct filter, e.g. none or installed;~devel |
This method returns packages that depend on this package. This is useful to know, as if package_id is being removed, we can warn the user what else would be removed.
This method typically emits Progress, Status and Error and Package.
Package enumerated types should be available or installed.
|
A correct filter, e.g. none or installed;~devel |
|
An array of package IDs. |
|
Either true or false. If yes then the requirements should be returned for all packages returned. This means if gnome-power-manager depends on NetworkManager and NetworkManager depends on HAL, then GetRequires on HAL should return both gnome-power-manager and NetworkManager. |
This method returns details about a specific update.
This method typically emits UpdateDetail and Error
|
An array of package IDs. |
This method should return a list of packages that are installed and are upgradable. It should only return the newest update for each installed package.
This method typically emits Progress, Error and Package.
Package enumerated types should be blocked, low, normal, important or security.
The status blocked signifies the package cannot be updated, probably due to other dependencies not being met. This type allows the GUI tools to show to the user that an update exists, but cannot be installed. The reason for it not being installed should be put into the update description when doing GetUpdateDetail.
A filter such as basename or gui is also useful if you want to do filtering on the method to only show the main packages rather than the complete list. The complete list is available but specifying none as the filter. Using no filter which may be useful in advanced tools or when using libpackagekit and searching for an update of a specific name. Other filter types may be present, but can be safely ignored of the backend does not support them.
|
A correct filter, e.g. none or installed;~devel |
This method should return a list of distribution upgrades that are available. It should not return updates, only major upgrades.
This method typically emits DistroUpgrade, Error and
This method installs local package files onto the local system.
The installer should always install extra dependant packages automatically.
This method typically emits Progress, Status and Error and Package.
Package enumerated types should be downloading, updating, installing or removing.
|
If the transaction is only allowed to install trusted files. Unsigned files should not be installed if this parameter is TRUE. If this method is can only install trusted files, and the files are unsigned, then the backend will send a ErrorCode(missing-gpg-signature). On recieving this error, the client may choose to retry with only_trusted FALSE after gaining further authentication. |
|
An array of full path and filenames to packages. |
This method installs new packages on the local system.
The installer should always install extra packages automatically as the use could call GetDepends prior to the install if a confirmation is required in the UI.
This method typically emits Progress, Status and Error and Package.
Package enumerated types should be downloading, updating, installing or removing.
|
If the transaction is only allowed to install trusted packages. Unsigned packages should not be installed if this parameter is TRUE. If this method is can only install trusted packages, and the packages are unsigned, then the backend will send a ErrorCode(missing-gpg-signature). On recieving this error, the client may choose to retry with only_trusted FALSE after gaining further authentication. |
|
An array of package IDs. |
This method allows us to install new security keys.
|
A key type, e.g. gpg |
|
A key ID, e.g. BB7576AC |
|
A PackageID for the package that the user is trying to install |
This method should fetch updated meta-data for all enabled repositories. This operation should be only scheduled when the computer is idle as the network connection will be very active, and will the computer will have have non-trivial levels of hard disk and processor activity. For these reasons, it should not be done automatically when on battery power.
When fetching each software source, ensure to emit RepoDetail for the current source to give the user interface some extra details. Be sure to have the "enabled" field set to true, otherwise you wouldn't be fetching that source.
This method typically emits Progress, Error and RepoDetail.
|
If the caches should be cleaned and reloaded even if there is valid, up to date data. |
This method removes packages from the local system.
This method typically emits Progress, Status and Error and Package.
Package enumerated types should be downloading, updating, installing or removing.
|
An array of package IDs. |
|
Either true or false. If true allow other packages to be removed with the package, but false should cause the script to abort if other packages are dependant on the package. |
|
Either true or false. This option is only really interesting on embedded devices with a limited amount of flash storage. It suggests to the packagekit backend that dependencies installed at the same time as the package should also be removed if they are not required by anything else. For instance, if you install OpenOffice, it might download libneon as a dependency. When auto_remove is set to true, and you remove OpenOffice then libneon will also get removed automatically. |
This method enables the repository specified.
|
A repository identifier, e.g. fedora-development-debuginfo |
|
true if enabled, false if disabled. |
This method allows arbitary data to be passed to the repository handler.
|
A repository identifier, e.g. fedora-development-debuginfo |
|
The backend specific value, e.g. set-download-url. |
|
The backend specific value, e.g. http://foo.bar.org/baz. |
This method turns a single package name into a package_id suitable for the other methods.
If the package is a fully formed package_id, then this should be treated as an exact package match. This is useful to find the summary or installed status of a package_id returned from other methods.
This method typically emits Error and Package.
Package enumerated types should be available or installed.
|
A correct filter, e.g. none or installed;~devel |
|
An array of package names, e.g. scribus-clipart. The package names are case sensitive, so for instance: Resolve('Packagekit') would not match PackageKit. As a special case, if Resolve()doc:tt> is called with a name prefixed with @ then this should be treated as a category, for example: @web-development. In this instance, a meta-package should be emitted, for example: web-development;;;meta with the correct installed status and summary for the category. |
This method rolls back the package database to a previous transaction.
|
A valid transaction ID. |
This method allows deeper searching than SearchName().
Do not refresh the package cache. This should be fast. This is very similar to search-name. This should search as much data as possible, including, if possible repo names, package summaries, descriptions, licenses and URLs.
Try to emit installed before available packages first, as it allows the client program to perform the GUI filtering and matching whilst the daemon is running the transaction.
If the backend includes installed and available versions of the same package when searching then the available version will have to be filtered in the backend.
This method typically emits Progress, Error and Package.
Package enumerated types should be available or installed.
|
A correct filter, e.g. none or installed;~devel |
|
A single word search term with no wildcard chars. The search can contain many words separated by spaces. In this case, the search operator is AND and the words can be found in any details section/field. For example, search of GPL games should returns every games with a GPL license. The search should not be treated as case sensitive. |
This method searches for files on the local system and files in available packages.
This should search for files. This should allow an application to find out what package owns a file on the system.
This method typically emits Progress, Error and Package.
Package enumerated types should be available or installed.
|
A correct filter, e.g. none or installed;~devel |
|
A filename or fully qualified path and filename on the system. If the search term begins with a / it will be assumed the entire path has been given and only packages that contain this exact path and filename will be returned. If the search term does not start with / then it should be treated as a single filename, which can be in any directory. The search is case sensitive, and should not be escaped or surrounded in quotes. |
This method returns packages from a given group enumerated type.
Do not refresh the package cache. This should be fast.
Try to emit installed before available packages first, as it allows the client program to perform the GUI filtering and matching whilst the daemon is running the transaction.
If the backend includes installed and available versions of the same package when searching then the available version will have to be filtered in the backend.
This method typically emits Progress, Error and Package.
Package enumerated types should be available or installed.
|
A correct filter, e.g. none or installed;~devel |
|
An enumerated group type, or unknown. The search cannot contain spaces. The following recommendations are made below: If the values strings are prefixed with category: then the request is treated as a 'category search', for example: category:web-development. Note: the old nomenclature for a 'category search' suggested using a @ prefix for the values options. This is still supported, and backends should continue to support category searches like @web-development. If the values strings are prefixed with repo: then the request is treated as a 'repository search', for example: repo:fedora-debuginfo. In this instance all packages that were either installed from, or can be installed from the fedora-debuginfo source would be returned. |
This method searches the package database by package name.
Do not refresh the package cache. This should be fast.
Try to emit installed before available packages first, as it allows the client program to perform the GUI filtering and matching whilst the daemon is running the transaction.
If the backend includes installed and available versions of the same package when searching then the available version will have to be filtered in the backend.
The search methods should return all results in all repositories. This may mean that multiple versions of package are returned. If this is not what is wanted by the client program, then the newest filter should be used.
This method typically emits Progress, Error and Package.
Package enumerated types should be available or installed.
|
A correct filter, e.g. none or installed;~devel |
|
A single word search term with no wildcard chars. The search term can contain many words separated by spaces. In this case, the search operator is AND. For example, search of gnome power should returns gnome-power-manager but not gnomesword or powertop. The search should not be treated as case sensitive. |
This method simulates a package file instalation emitting packages required to be installed, removed, updated, reinstalled, downgraded, obsoleted or untrusted. The latter is used to present the user untrusted packages that are about to be installed.
This method typically emits Error and Package.
|
An array of full path and filenames to packages. |
This method simulates a package instalation emitting packages required to be installed, removed, updated, reinstalled, downgraded, obsoleted or untrusted. The latter is used to present the user untrusted packages that are about to be installed.
This method typically emits Error and Package.
|
An array of package IDs. |
This method simulates a package removal emitting packages required to be installed, removed, updated, reinstalled, downgraded, obsoleted or untrusted. The latter is used to present the user untrusted packages that are about to be installed.
This method typically emits Error and Package.
|
An array of package IDs. |
|
Either true or false. This option is only really interesting on embedded devices with a limited amount of flash storage. It suggests to the packagekit backend that dependencies installed at the same time as the package should also be removed if they are not required by anything else. For instance, if you install OpenOffice, it might download libneon as a dependency. When auto_remove is set to true, and you remove OpenOffice then libneon will also get removed automatically. |
This method simulates a package update emitting packages required to be installed, removed, updated, reinstalled, downgraded, obsoleted or untrusted. The latter is used to present the user untrusted packages that are about to be installed.
This method typically emits Error and Package.
|
An array of package IDs. |
This method updates existing packages on the local system.
The installer should always update extra packages automatically to fulfil dependencies.
This should allow an application to find out what package owns a file on the system.
This method typically emits Progress, Status and Error and Package.
|
If the transaction is only allowed to update to trusted packages. Unsigned packages should not be installed if this parameter is TRUE. If this method is can only update trusted packages, and the packages are unsigned, then the backend will send a ErrorCode(missing-gpg-signature). On recieving this error, the client may choose to retry with only_trusted FALSE after gaining further authentication. |
|
An array of package IDs. |
This method updates all packages on the system to thier newest versions.
The installer should update all the updateable packages on the system, including automatically installing any new packages that are needed for dependancies.
|
If the transaction is only allowed to update to trusted packages. Unsigned packages should not be installed if this parameter is TRUE. If this method is can only update trusted packages, and the packages are unsigned, then the backend will send a ErrorCode(missing-gpg-signature). On recieving this error, the client may choose to retry with only_trusted FALSE after gaining further authentication. |
This method returns packages that provide the supplied attributes. This method is useful for finding out what package(s) provide a modalias or GStreamer codec string.
This method typically emits Progress, Status and Error and Package.
Package enumerated types should be available or installed.
|
A correct filter, e.g. none or installed;~devel |
|
A PkProvideType, e.g. PK_PROVIDES_ENUM_CODEC. |
|
The data to send to the backend to get the packages. Note: This is backend specific. |
This method perfoms a distribution upgrade to the specified version.
This method typically emits Progress, Status and Error and Package.
|
The distribution ID to upgrade to, e.g. fedora-14. |
|
The type of upgrade, e.g. minimal, default or complete. Minimal upgrades will download the smallest amount of data before launching a installer. The default is to download enough data to launch a full graphical installer, but a complete upgrade will be required if there is no internet access during install time. |
This method simulates recovering the package management system from e.g. unsatisfied dependencies of installed packages emitting packages required to be installed, removed, updated, reinstalled, downgraded, obsoleted or untrusted. The latter is used to present the user untrusted packages that are about to be installed.
This method typically emits Progress, Status and Error and Package.
This method recovers the package management system from e.g. unsatisfied dependencies of installed packages.
This method typically emits Progress, Status and Error and Package.
|
If the transaction is only allowed to install trusted packages. Unsigned packages should not be installed if this parameter is TRUE. If this method is can only install trusted packages, and the packages are unsigned, then the backend will send a ErrorCode(missing-gpg-signature). On recieving this error, the client may choose to retry with only_trusted FALSE after gaining further authentication. |
This signal send information about a collection category
|
The parent identifier, e.g. applications. If the category is a root entry, use a blank parent. |
|
The category identifier, e.g. applications;system-tools. The identifier does not have to be related to the parent_id in any way. A menu tree is made from multiple Category signals. The tree does not have any depth or bredth limits, although it should be kept to less than about 100 entries as this will be shown to the user in a menu. The cat_id will be sent as a parameter to SearchGroup so you may have to prefix or otherwise identify the ID to not confuse the search method. |
|
The localised name of the category, e.g. System Tools. |
|
The localised category summary, e.g. Tools for mangaing system state. This is not normally shown in the menus, but may be shown in helper popups. |
|
The icon name for the category, e.g. server-cfg. If the icon is not known, then it should be set to image-missing. |
This signal allows the backend to convey more details about the package.
|
The package ID |
|
The license string, e.g. GPLv2+ or BSD and (MPLv1.1 or GPLv2+). More details about the correct way to format licensing strings can be found on the Fedora packaging wiki. |
|
The enumerated package group description |
|
The multi-line package description. If formatting is required, then markdown syntax should be used, e.g. This is **critically** important |
|
The upstream project homepage |
|
The size of the package in bytes. This should be the size of the entire package file, not the size of the files installed on the system. If the package is not installed, and already downloaded and present in the package manager cache, then this value should be set to zero. |
This signal is used to report errors back to the session program.
Errors should only be send on fatal abort.
|
Enumerated type, e.g. no-network. |
|
Long description or error, e.g. failed to connect to mytry.xml |
This signal is used to push file lists from the backend to the session.
|
The Package ID that called the method. |
|
The file list, with each file seporated with ;. |
This signal is used to signal that the transaction has finished.
|
The PkExitEnum describing the exit status of the transaction. |
|
The amount of time in milliseconds that the transaction ran for. |
This signal is sent when the backend wants to send a message to the session.
This allows the backend to queue up a message to be shown after the transaction has completed.
|
One of warning, notice, or daemon. |
|
Required details about the message, non-localised. |
This signal allows the backend to communicate packages to the session.
If updating, as packages are updated then emit them to the screen. This allows a summary to be presented after the transaction.
When returning results from a search always return installed before available for the same package name.
|
A valid info string enumerated type |
|
This identifier is of the form name;version;arch;data in a single string and is meant to represent a single package unique across all local and remote data stores. For a remote, not-installed package the data field should be set as the repository identifier or repository name. The data field for an installed package must be prefixed with installed as this is used to identify which packages are installable or installed in the client tools. As a special extension, if the package manager is able to track which repository a package was originally installed from, then the data field can be set to installed:REPO-NAME which allows the frontend client to advise the user of the package origin. The data field for a non-installed local package must be local as this signifies a repository name is not available and that package resides locally on the client system rather than in any specific repository. |
|
The one line package summary, e.g. Clipart for OpenOffice |
This signal describes a repository on the system.
|
The repository ID. |
|
A description of the repository. |
|
If the repository is enabled and in use. |
RepoSignatureRequired ('s' package_id,
's' repository_name,
's' key_url,
's' key_userid,
's' key_id,
's' key_fingerprint,
's' key_timestamp,
's' type)
This signal is emitted when a transaction is not possible due to a missing security certificate.
Some backends support repositories which use a cryptographic signature, such as GPG. If a package cannot be installed because it is signed with a key that has not been verified, this signal is generated so the user can choose to accept or decline the key.
This signal includes information that can be used to verify that the key should be trusted, such as a URL for the company or person who owns the key, the key's ID, the userid of the key creator, and the date the key was generated.
|
A package ID for the package that is trying to be installed |
|
The name of the repository associated with the provided key. |
|
The URL provided with the key. |
|
The user id associated with the key. |
|
A unique identifier for the key. |
|
The hashed fingerprint of the key. |
|
The date the key was created. |
|
The type of signature used. gpg, for example. |
EulaRequired ('s' eula_id,
's' package_id,
's' vendor_name,
's' license_agreement)
This signal is emitted when a transaction is not possible due to a EULA that needs to be agreed to at install time.
Some backends support EULAs, which have to be agreed to before the install can proceed.
|
The eula_id which identifies the EULA - this is provided so that if a specific EULA has previously agreed to a EULA from Acme Corp it is not asked again. An example eula_id's is vmware5_single_user. |
|
A package ID for the package that is trying to be installed. |
|
The vendor that is providing the EULA. |
|
The full text EULA. |
This signal is emitted when a transaction needsneeds a different media to grab the packages.
Some backends support Media changing, which will fail the transaction each time it needs a new media.
|
Enumerated type, e.g. dvd. |
|
The media_id which identifies the Media - this is provided so that if DeviceKit or another program is able to identify the right media before continuing, note however that it's not the DeviceKit oblication to check the media when the transaction is re-scheduled this is the backend task. An example media_id's is Debian testing amd64 Bin-1. |
|
Might be used for the disk label too, something like Fedora Disk 1 |
This signal is sent when the session program should notify the user that a restart is required.
This is optional, but highly recommended.
This can be sent as many times as needed by the backend script. PackageKit will always choose the 'worst' method in the UI notification.
|
One of system, application or session. |
|
The package ID that caused the restart notifier. |
Transaction ('s' old_tid,
's' timespec,
'b' succeeded,

|
If the transaction succeeded. |
|
The role enumerated type. |

's' vendor_url,
's' bugzilla_url,
's' cve_url,
's' restart,
's' update_text,
's' changelog,
's' state,
's' issued,
's' updated)
This signal is sent when more details are required about a specific update.
|
The package ID |
|
A list of package_id's that are to be updated, seporated by &. This odd delimited was chosen as \t is already being used in the spawned backends, and & is a banned character in a package_id. |
|
A list of package_id's that are to be obsoleted, separated by & |
|
A URL with more details on the update, e.g. a page with more information on the update. The format of this command should be http://www.foo.org/page.html?4567;Update to SELinux |
|
A bugzilla URL with more details on the update. If no URL is available then this field should be left empty. |
|
A CVE URL with more details on the security advisory. |
|
A valid restart type, e.g. system. |
|
The update text describing the update. If formatting is required, then markdown syntax should be used, e.g. This is **critically** important |
