following :'

sudo apt install apparmor-utils

$ sudo aa-disable /usr/bin/man
Disabling /usr/bin/man.

ERROR: Cache read/write disabled: interface file missing. (Kernel needs AppArmor 2.4 compatibility patch.)
Warning: unable to find a suitable fs in /proc/mounts, is it mounted?
Use --subdomainfs to override.

Up shot man no still not working.

Any Help, ideas available anybody ?
