Quando pressiono o botão de atualização, a janela do atualizador de software simplesmente desaparece.
Eu também tentei
sudo do-release-upgrade
No entanto, recebo a seguinte mensagem:
Checking for a new Ubuntu release
Please install all available updates for your release before upgrading.
Isto, apesar de já ter corrido
sudo apt update
sudo apt upgrade
Ao fazer a atualização, recebo:
