Cześć Wam!

Mam LM 20.1 i  słynne kłopoty z odmontowaniem /oldroot, dzięki czemu nie mogę zamknąc lub zrestartować systemu.
porada w innym wątku by dopisać w /etc/default/grub odpowiednią komendę nic nie dała.
Oto parę informacji o moim systemie:

Jak czytam wątki na różnych forach to sprawa raczej nieciekawa. Może ktoś w Was coś doradzi.
