Eu tenho um laptop pessoal que é um Thinkpad T480. Escrevi sobre o mesmo aqui: entrei pra moda do laptop refurbished. Como não estou usando ele pra muita coisa e tenho também um Thinkpad pro trabalho, deixo o meu pra rodar o último Ubuntu.
E estava com o oneiric, 24.10, quando tentei fazer upgrade pro plucky, 25.04. E tive um belo dum crash no zfs.

E ficava nisso.
Tinha de mandar um zfs rollback nos volumes pra conseguir voltar a usar.
E tentar o upgrade novamente.
Depois de muito tentar, resolvi abrir um bug report no launchpad. Meu bug foi marcado como duplicado e passei então a interagir no bug onde o problema foi reportado primeiramente.
tl;dr: o bug era do zfs no kernel padrão que o plucky instala. A correção exige upgrade tanto do zfs quanto do kernel antes de ir pro upgrade do plucky.
Da primeira vez eu errei esse upgrade. E precisei recuperar o zfs pra voltar o snapshot.
E mais um problema já que não existe um procedimento bem descritivo de como fazer isso. Ou tem?
Sim tem. E mais de um.
Tive de recuperar algumas vezes o sistema. Então fiquei meio que craque em fazer isso. O esquema está abaixo:
