flatpak Developer Alexander Larsson alexl@redhat.com flatpak config 1 flatpak-config Manage configuration flatpak config OPTION flatpak config OPTION --set KEY VALUE flatpak config OPTION --unset|--get KEY The flatpak config command shows or modifies the configuration of a flatpak installation. The following keys are supported: languages The languages that are included when installing Locale extensions. The value is a semicolon-separated list of two-letter language codes, or one of the special values * or *all*. If this key is unset, flatpak defaults to including the extra-languages key and the current locale. extra-languages This key is used when languages is not set, and it defines extra locale extensions on top of the system configured languages. The value is a semicolon-separated list of locale identifiers (language, optional locale, optional codeset, optional modifier) as documented by setlocale3 (for example, en;en_DK;zh_HK.big5hkscs;uz_UZ.utf8@cyrillic). report-os-info If this key is set to false or the no-report-os-info file exists at FLATPAK_CONFIG_DIR Flatpak will not report the OS name, version, and architecture from /etc/os-release to the Flatpak remote via the Flatpak-Os-Info HTTP header when pulling objects. The default value of the key if unset is true. For configuration of individual remotes, see flatpak-remote-modify1. For configuration of individual applications, see flatpak-override1. The following options are understood: -h --help Show help options and exit. --list Print all keys and their values. --set Set key KEY to VALUE. --unset Unset key KEY. --get Print value of KEY. -u --user Configure per-user installation. --system Configure system-wide installation. --installation=NAME Configure the system-wide installation specified by NAME among those defined in /etc/flatpak/installations.d/. Using --installation=default is equivalent to using --system. -v --verbose Print debug information during command processing. --ostree-verbose Print OSTree debug information during command processing. $ flatpak config --set languages "sv;en;fi" flatpak1, flatpak-remote-modify1, flatpak-override1
