## Description

FlatpakInstallation is the toplevel object that software installers should use to operate on an flatpak applications.

An FlatpakInstallation object provides information about an installation location for flatpak applications. Typical installation locations are either system-wide (in $prefix/var/lib/flatpak) or per-user (in ~/.local/share/flatpak).

FlatpakInstallation can list configured remotes as well as installed application and runtime references (in short: refs), and it can add, remove and modify remotes.

FlatpakInstallation can also run, install, update and uninstall applications and runtimes, but FlatpakTransaction is a better, high-level API for these tasks.

To get a list of all configured installations, use `flatpak_get_system_installations()`, together with `flatpak_installation_new_user()`.

The FlatpakInstallation API is threadsafe in the sense that it is safe to run two operations at the same time, in different threads (or processes).

`flatpak_installation_install` has been deprecated since version 1.7.0 and should not be used in newly-written code.

Use `flatpak_transaction_add_install()` instead.

This is an old deprecated function, you should use FlatpakTransaction and `flatpak_transaction_add_install()` instead. It has a lot more interesting features.

Install a new application or runtime.

Note that this function was originally written to always return a FlatpakInstalledRef. Since 0.9.13, passing FLATPAK_INSTALL_FLAGS_NO_DEPLOY will only pull refs into the local flatpak repository without deploying them, however this function will be unable to provide information on the installed ref, so FLATPAK_ERROR_ONLY_PULLED will be set and the caller must respond accordingly.

#### Parameters

self | a FlatpakInstallation |
remote_name | name of the remote to use |
kind | what this ref contains (an FlatpakRefKind) |
name | name of the app/runtime to fetch |
arch | which architecture to fetch (default: current architecture). | [nullable]
branch | which branch to fetch (default: 'master'). | [nullable]
progress | progress callback. | [scope call][nullable]
progress_data | user data passed to `progress` . | [closure progress][nullable]
cancellable | a GCancellable. | [nullable]
error | return location for a GError |

You can use `flatpak_installation_get_installed_ref()` or `flatpak_installation_get_current_installed_app()` to find out what builds are available, in order to get a value for `commit` .

Compared to `flatpak_installation_launch()`, this function returns a FlatpakInstance that can be used to get information about the running instance. You can also use it to wait for the instance to be done with `g_child_watch_add()` if you pass the FLATPAK_LAUNCH_FLAGS_DO_NOT_REAP flag.

#### Parameters

self | a FlatpakInstallation |
flags | set of FlatpakLaunchFlags |
name | name of the app to launch |
arch | which architecture to launch (default: current architecture). | [nullable]
branch | which branch of the application (default: "master"). | [nullable]

                                    GError **error);

Lists the installed apps and runtimes that have an update available, either from the configured remote or locally available but not deployed (see `flatpak_transaction_set_no_deploy()`).

This also checks if any of FlatpakInstalledRef has a missing FlatpakRelatedRef (which has `should-download` set to `TRUE`) or runtime. If so, it adds the ref to the returning GPtrArray to pull in the FlatpakRelatedRef or runtime again via an update operation in FlatpakTransaction.

In case more than one app needs an update of the same runtime or extension, this function will return all of those apps.

                                    GError **error);

Lists all the locally installed refs that are related to `ref` . These are things that are interesting to install, update, or uninstall together with `ref` . For instance, locale data or debug information.

Note that while the related refs are usually installed from the same remote as `ref` (`remote_name` ), it is possible they were installed from another remote.

This function is similar to flatpak_installation_list_remote_related_refs_sync, but instead of looking at what is available on the remote, it only looks at the locally installed refs. This is useful for instance when you're looking for related refs to uninstall, or when you're planning to use FLATPAK_UPDATE_FLAGS_NO_PULL to install previously pulled refs.

#### Parameters

self | a FlatpakInstallation |
remote_name | the name of the remote providing `ref` |
ref | the ref |
cancellable | a GCancellable. | [nullable]
error | return location for a GError |

#### Returns

a GPtrArray of FlatpakRelatedRef instances.

                                           GError **error);

Lists the installed references that are not 'used'.

A reference is used if it is either an application, or the runtime or sdk of a used ref, or an extension of a used ref. Pinned runtimes are also considered used; see flatpak-pin(1) and `flatpak_installation_list_pinned_refs()`.

#### Parameters

self | a FlatpakInstallation |
arch | if non-`NULL`, the architecture of refs to collect. | [nullable]
cancellable | a GCancellable. | [nullable]

Lists all the available refs on `remote_name` that are related to `ref` , and the subpaths to use. These are things that are interesting to install, update, or uninstall together with `ref` . For instance, locale data or debug information.

The returned list contains all available related refs, but not every one should always be installed. For example, `flatpak_related_ref_should_download()` returns `TRUE` if the reference should be installed/updated with the app, and `flatpak_related_ref_should_delete()` returns `TRUE` if it should be uninstalled with the main ref.

The commit property of each FlatpakRelatedRef is not guaranteed to be non-`NULL`.

Note that if there are locally available data that are in the ref, which is common for instance if you're doing an update then the real download size may be smaller than what is returned here.

NOTE: Since 0.11.4 this information is accessible in FlatpakRemoteRef, so this function is not very useful anymore.

#### Parameters

self | a FlatpakInstallation |
remote_name | the name of the remote |
ref | the ref |
download_size | return location for the (maximum) download size. | [out]
installed_size | return location for the installed size. | [out]
cancellable | a GCancellable. | [nullable]
error | return location for a GError |

#### Returns

`TRUE`, unless an error occurred

                                           GError **error);

`flatpak_installation_install_ref_file` has been deprecated since version 1.7.0 and should not be used in newly-written code.

Use `flatpak_transaction_add_install_flatpakref()` instead.

This is an old deprecated function, you should use FlatpakTransaction and `flatpak_transaction_add_install_flatpakref()` instead. It has a lot more interesting features.

Creates a remote based on the passed in .flatpakref file contents in `ref_file_data` and returns the FlatpakRemoteRef that can be used to install it.

Note, the FlatpakRemoteRef will not have the commit field set, or other details, to avoid unnecessary roundtrips. If you need that you have to resolve it explicitly with `flatpak_installation_fetch_remote_ref_sync()`.

#### Parameters

self | a FlatpakInstallation |
ref_file_data | The ref file contents |
cancellable | a GCancellable. | [nullable]
error | return location for a GError |

                                      GError **error);

Drops all internal (in-memory) caches. For instance, this may be needed to pick up new or changed remotes configured outside this installation instance.

#### Parameters

self | a FlatpakInstallation |
cancellable | a GCancellable. | [nullable]
error | return location for a GError |

#### Returns

`TRUE` on success, `FALSE` on error

### flatpak_installation_add_remote ()

    gboolean
    flatpak_installation_add_remote (FlatpakInstallation *self,

                                     GCancellable *cancellable,
                                     GError **error);

Adds a new `remote` object to the set of remotes. This is similar to `flatpak_installation_modify_remote()` for non-existing remote names. However, if the named remote already exists then instead of modifying it it fails with `FLATPAK_ERROR_ALREADY_INSTALLED`, or if `if_needed` is true it silently succeeds without doing anything.

As an exception to the last, if the local config has a filter defined, but the new remote unsets the filter (for example, it comes from an unfiltered .flatpakref via `flatpak_remote_new_from_file()`) the the local remote filter gets reset. This is to allow the setup where there is a default setup of a filtered remote, yet you can still use the standard flatpakref file to get the full contents without getting two remotes.

#### Parameters

self | a FlatpakInstallation |
remote | the new FlatpakRemote |
if_needed | if `TRUE`, only add if it doesn't exists |
cancellable | a GCancellable. | [nullable]
error | return location for a GError |

#### Returns

`TRUE` if the modifications have been committed successfully
