I can't remove old timeshift directory because it has corrupt entry inside:
$ sudo rm -rf *
rm: cannot remove 'snapshots/2022-09-04_22-00-01/localhost/usr/share/icons/Humanity/status/48': Directory not empty
and let me cd in there:
$ ls -al
ls: cannot access 'gpm-primary-080-charging'$'\004': No such file or directory
total 16
drwxr-xr-x 2 xyz root 12288 Sep 9 2022 .
drwxr-xr-x 3 xyz root 4096 Sep 9 2022 ..
-????????? ? ? ? ? ? 'gpm-primary-080-charging'$'\004'
it's ext4 filesystem.
how do I remove that directory?
