Snapcraft not working in opensuse thumbleweed

I have the same error I used to have on Fedora: Snapd not working on Fedora 41 beta

but now with thumbleed:

user@localhost:~/.local/bin> sudo snap install hello-word --edge
[sudo] password for root: 
error: system does not fully support snapd: cannot mount squashfs image using "squashfs": -----
       mount: /tmp/syscheck-mountpoint-2644714221: wrong fs type, bad option, bad superblock on
       /dev/loop0, missing codepage or helper program, or other error.

       dmesg(1) may have more information after failed mount system call.

       -----

Anyone has any idea how to fix it?

grep squashfs /proc/filesystems doesn’t return anyting as expected.

Loading modprobe then trying snap doesn’t work either:

user@localhost:~/.local/bin> sudo modprobe squashfs
user@localhost:~/.local/bin> sudo snap install hello-word --edge
error: system does not fully support snapd: cannot mount squashfs image using "squashfs": -----
       mount: /tmp/syscheck-mountpoint-3392391960: wrong fs type, bad option, bad superblock on
       /dev/loop0, missing codepage or helper program, or other error.

       dmesg(1) may have more information after failed mount system call.

Can you cat /etc/os-release ? I’m on 20250508 and everything seems to be working fine. Are you using SELinux by any chance?

edit:

maciek@carrack:~ grep squashfs /proc/filesystems
        squashfs

edit2:

FWIW I’m using kernel-default (kernel-default-6.14.5-1.1.x86_64 right now specifically), and kernel-longterm.
