Boot in persistent mode.
Create folder /lib/systemd/system/apparmor.service.d.
sudo mkdir -p /lib/systemd/system/apparmor.service.d
Open file /lib/systemd/system/apparmor.service.d/30_live_mode.conf with root rights.
lxsu mousepad /lib/systemd/system/apparmor.service.d/30_live_mode.conf
Paste the following content.
