[SOLVED]Permission error with snap --classic confinament

Hi i’ve problem with app installed with --classic option, (e.g code, pycharm). When i try to run it they it give me this error “/var has ‘other’ write 41777”. I’m using ArchLinux and i’ve make the symlink as the wiki say (https://wiki.archlinux.org/title/Snap#Tips_and_tricks). I found a workaround setting the /var directory with 755 permission and the apps work but slowly my OS crash. Can someone help me? Thanks

You really should not run with /var world-writable. This is likely a broken installation of Arch Linux. A default installation of Arch Linux has /var set to mode 0o755 (755) as you attempted to correct your installation to. The fact that your installation became unstable after you made the change to permission suggests you are running a very non-standard installation so we are unlikely to be able to help.

Solved. Yes the problem was that basically i’ve both var and tmp on same partition but i didn’t configure right /etc/fstab. I link the complete solution for me https://bbs.archlinux.org/viewtopic.php?pid=2002952#p2002952
