Recently I tried to run opera but nothing happened. So I tried to run it on terminal and got this error
cannot open /proc/self/cgroup: Permission denied
But I tried other snap apps such as code, it works fine, and also recently saw a forum post that someone has the same problem with another browser. Is it to do with the latest snap update on Manjaro? Or how do I fix it
I was also experiencing this issue yesterday. My Plex went down during the day and I wasn't sure why. I found the error you posted when running:
sudo snap logs plexmediaserver
Rebooting my whole server fixed the issue.
On Ubuntu sudo dpkg-reconfigure apparmor solved my problem.
From this askubuntu answer. Perhaps it's worth a try, even on manjaro.
