After trying to reinstall my amd-gpu-drivers, my system rebooted into CLI. So I tried to reinstall GUI with “apt install task-gnome-desktop”. After this my system says sudo is an unknown command. Tried with su- but system says “Authentication failure”, possibly because root was never set. So I think I lost root access.
Is it possible “task-gnome-desktop” removed sudo and locked me out?
How can I set root password?
Any hint very welcome.
