Cannot create hotspot. Getting ERROR: Cache read/write disabled

[bastian-zab]

Describe the bug
The app starts and goes to Wifi created, cleaning up then goes back to not running immediately. This is the error I see on the terminal:

kexec --user root create_ap wlp2s0 enp3s0 'MyAccessPoint5' '45677555556' --mkconfig /etc/create_ap.conf --freq-band 2.4
Config options written to '/etc/create_ap.conf'

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.

Error: Failed to run hostapd, maybe a program is interfering.
If an error like 'n80211: Could not configure driver mode' was thrown
try running the following before starting create_ap:
nmcli r wifi off
rfkill unblock wlan
Command not found or exited with error status

Screenshots

Desktop (please complete the following information):

• OS: Manjaro
• GNOME 48.1

Removing apparmor fixed this for me otherwise I think you need to configure apparmor properly
