Overview​

This script clears the Flatpak cache.

Flatpak creates temporary files as /var/tmp/flatpak-cache-* 1. These files can fill up a large portion of the disk 1, and reveal usage patterns.

Flatpak stores cache files in ~/.cache/flatpak/system-cache/ which replaces the directory used in older versions (~/.local/share/flatpak/system-cache/) 2.

Not Advised

This script should only be used by advanced users.

This script is not recommended for daily use as it breaks important functionality.

Consider creating a system backup before doing any changes.
