Here is the solution to disable apparmor on the system and it worked on my test system (not harmful since apparmor package is not installed):
Codesudo mkdir -p /etc/default/grub.d echo 'GRUB_CMDLINE_LINUX_DEFAULT="$GRUB_CMDLINE_LINUX_DEFAULT apparmor=0"' | sudo tee /etc/default/grub.d/apparmor.cfg sudo update-grub sudo reboot

Thanks a lot. Worked for me also
You saved my day
