Obrigado antecipadamente

EDIT: cat /etc/apt/sources.list.d/additional-repositories.list :

deb http://archive.canonical.com/ sarah partner

Answer 1

Em primeiro lugar, observe que apt-get update ainda atualiza seus índices conforme apropriado, apenas reclama que não é possível fazer o download das informações necessárias para alguns de seus repositórios.

sarah é um nome de código Mint, não um nome de código do Ubuntu, então não faz sentido tentar usar um repositório sarah hospedado pela Canonical; você pode excluir com segurança os repositórios adicionais:

sudo rm /etc/apt/sources.list.d/additional-repositories.list

Isso corrigirá os erros que você está vendo.

    

Answer 2

Não existe uma versão sarah do Ubuntu. Use os repositórios do linuxmint somente quando estiver usando a distribuição linuxming.
