Update not working, HHD nor terminal

[twojays]

Hello,
i try to install the latest update but nothing works.
I always get the same error. Tried also to update from a older image but the same error.
Can someone point me in the right direction?

my hardware is a ROG Ally gen1 so nothing special…

You ran out of free space. If you believe that is not the case, make sure to remove leftover btrfs snapshots if you have them.

i installed too many games i suppose
but the error was not obvious enough for me
