Is there an equivalent of sudo apt clean in snap and flatpak (to delete the cached installation files)?

That might free up a considerable amount of space.

Also, is there any equivalent of sudo apt autoremove, or is it taken care of automatically?

I have not come across one but the following should help:

Snapd

Snap generally preserves at least three revisions (older versions) of any software / package you have installed at any point of time. This makes snapd/cache very bulky. You can set to 1 or 2 using

sudo snap set system refresh.retain=2  // starting from snapd version 2.34  

This way you preserver lot of space. Now, clearing the cached installation

sudo rm -rf /var/cache/snapd

flatpak

The analogous process of sudo apt autoremove in flatpak is

flatpak uninstall --unused
2
  • Even after that flatpak still use a considerable space (du -hc /var/tmp/flatpak-cache-* | tail -1). Probably safe to delete anyway. Apr 22, 2022 at 23:25
  • For snap, refresh.retain=1 isn't allowed (retain must be a number between 2 and 20, not "1"), and 2 can still be incredibly bulky. Also, changing the setting doesn't immediately free any space. You need to manually remove old versions.
