Just a PSA for anyone beating their head against a wall trying to figure out why snaps are not working on their Manjaro stable install.
The current top kernel (6.8.4-1) is bugged and causes snaps to give this error:
error: system does not fully support snapd: cannot mount squashfs image using "squashfs"
Apparently the newer version of the 6.8 kernel available in Manjaro testing works fine.
I had updated the kernel several days ago and have rebooted several times since then.
Ended up rebooting into a lower kernel to use the snap, luckily I don’t often need to use it.
