flatpak-mask - Mask out updates and automatic installation

flatpak mask [OPTION...] PATTERN...

Flatpak maintains a list of patterns that define which refs are masked. A masked ref will never be updated or automatically installed (for example a masked extension marked auto-download will not be downloaded). You can still manually install such refs, but once they are installed the version will be pinned.

The patterns are just a partial ref, with the * character matching anything within that part of the ref. Here are some example patterns:


To list the current set of masks, run this command without any patterns.

The following options are understood:

-h, --help

Show help options and exit.


Instead of adding the patterns, remove matching patterns.

-u, --user

Mask refs in a per-user installation.


Mask refs in the default system-wide installation.


Mask 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.
