Hi,

After switching to 15.1 and installing firejail from community repo “Virtualization” bumped into error if run by a user:
“Error set_perms: util.c:1027 create_empty_dir_as_root: Operation not permitted”

Found similar problem in here: https://github.com/NixOS/nixpkgs/issues/43487 and they fixed it in OS somehow)

OS: Leap 15.1 (x86_64)
firejail: 0.9.60-lp151.12.4

Thanks for advice in advance

OK, found the root cause by myself.
According to firejail issue: https://github.com/netblue30/firejail/issues/2310
There is lack of suid bit on /usr/bin/firejail in Opensuse Leap 15.1

I don’t know how this is from security point of view, but setting that bit solves the problem.
