Thought I'd give firejail a try... When I do
I get (among other strange messages)
Warning: Cannot confine the application using AppArmor. Maybe firejail-default AppArmor profile is not loaded into the kernel. As root, run "aa-enforce firejail-default" to load it.
OK, so I run
sudo aa-enforce firejail-default
which results in
ERROR: Cache read/write disabled: interface file missing. (Kernel needs AppArmor 2.4 compatibility patch.)
What do I do now? My kernel is 4.19.62-1-MANJARO x86_64. How do I do the kernel patch? Maybe I should switch to testing? Any help would be greatly appreciated!
