flatpak Developer Matthew Leeds matthew.leeds@endlessm.com flatpak pin 1 flatpak-pin Pin runtimes to prevent automatic removal flatpak pin OPTION PATTERN Flatpak maintains a list of patterns that define which refs are pinned. A pinned ref will never be automatically uninstalled (as are unused runtimes periodically). This can be useful if for example you are using a runtime for development purposes. Runtimes that are explicitly installed, rather than installed as a dependency of something else, are automatically pinned. The patterns are just a partial ref, with the * character matching anything within that part of the ref. Only runtimes can be pinned, not apps. Here are some example patterns: org.some.Runtime org.some.Runtime//unstable runtime/org.domain.* org.some.Runtime/arm To list the current set of pins, run this command without any patterns. The following options are understood: -h --help Show help options and exit. --remove Instead of adding the patterns, remove matching patterns. -u --user Pin refs in a per-user installation. --system Pin refs in the default system-wide installation. --installation=NAME Pin refs in a 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. $ flatpak pin $ flatpak pin org.freedesktop.Platform//19.08 $ flatpak pin --remove org.freedesktop.Platform//19.08 flatpak1, flatpak-uninstall1,
