Question

Eu sei que as pessoas fizeram essa pergunta, mas as soluções parecem ser diferentes e eu ainda não encontrei a minha. Eu recebo a resposta conforme indicado no título do assunto. Aqui está a saída no terminal:

sudo apt-get update

Muito obrigado por qualquer ajuda.

    

Answer 1

Como mencionado no link postado por Manoj Sawai, seu problema está relacionado com o google chrome e a chave GPG alterada.

O comando a seguir deve importar a chave GPG atualizada do Google e, portanto, corrigir seu problema:

wget -q -O - https://dl-ssl.google.com/linux/linux_signing_key.pub | sudo apt-key add -

Depois disso, execute novamente os comandos sudo apt update e você deve estar bem novamente.
