When I try to run any snap app |I’ve got an error internal error, please report: running "code" failed: cannot find installed snap "code" at revision 167: missing file /snap/code/167/meta/snap.yaml When I try to install a new one , for example

sudo snap install hello-world

I’ve got

error: system does not fully support snapd: cannot mount squashfs image using "squashfs": mount:
       /tmp/syscheck-mountpoint-265178644: wrong fs type, bad option, bad superblock on /dev/loop9,
       missing codepage or helper program, or other error.

The error describes exactly what the problem is. It is not possible to mount squashfs images, hence it will not be possible to run any snaps. You first need to find out why squahfs isn’t supported, perhaps a kernel modules is missing, or it is entirely disabled in the kernel. Can you paste the contents of /etc/os-release?

what is the full output of snap version along with the above … (are you running a proper ubuntu kernel on that machine? all ubuntu kernels have squashfs support by default)

Same issue, it seems to happen when I try to mount an cifs device: I use Kubuntu 24.04

  1. Install a snap (I installed for Example IntelliJ community via discover)
  2. Reboot (idk if thats neccesarry)
  3. sudo mount -t cifs -o uid=1000 //<A samba SMB IP>/root /media/<You Username>/mount
  4. intellij-idea-community

And voila: interner Fehler, bitte melden: Ausführung von “intellij-idea-community” fehlgeschlagen: cannot find installed snap “intellij-idea-community” at revision 535: missing file /snap/intellij-idea-community/535/meta/snap.yaml
