flatpak-pin - Pin runtimes to prevent automatic removal

       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.

$flatpakpin$flatpakpinorg.freedesktop.Platform//19.08$flatpakpin--removeorg.freedesktop.Platform//19.08

       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.
