sudo do-release-upgrade -cd
retorna
Checking for a new Ubuntu release
New release '22.04' available.
Run 'do-release-upgrade' to upgrade to it.
Então
sudo do-release-upgrade
retorna
Checking for a new Ubuntu release
There is no development version of an LTS available.
To upgrade to the latest non-LTS development release
set Prompt=normal in /etc/update-manager/release-upgrades.
Acho que o bug é:
22.04 não está marcado como LTS. Portanto do-release-upgrade, não funciona para a atualização de 20.04 LTS para 22.04 LTS.
Alguma solução exceto set Prompt=normal in /etc/update-manager/release-upgrades.?
