I'm new to linux.
Out of curiosity, I run some commands as sudo to mess up with permissions. When I restarted my system, most of the apps give firejail error.
For Example If I run firefox then it says:
Error: cannot create /run/firejail/profile/3535
This same error appears in most of the apps like rhythombox, vlc, dolphin when i launch them in terminal by just typing their name. When I launch them directly, nothing happens after some loading. I hope I'm not the first one to get this error because of my stupidity. Please Help.
