Eu consegui isso primeiro
Failed to download package files. Check internet connection
erro e tentei o solução que parece funcionar para a maioria dos outros que tiveram o mesmo problema ... alterando o local de download. Eu tentei vários servidores diferentes sem efeito. Eu também tentei a segunda solução no link acima (ter que fazer um novo arquivo de lista de fontes).
Mais recentemente, o erro foi "instalação requer instalação de fontes não autenticadas". A primeira solução em este post é o mesmo que a segunda solução do primeiro link acima e não faz diferença na minha situação. Antes de começar a adicionar chaves públicas ou qualquer outra solução, concluí que seria melhor publicar minha saída especificamente e ver o que a comunidade tem a dizer.
Aqui está minha saída para apt-get update .
Aqui está a minha saída para apt-get upgrade .
Eu não tenho uma reputação alta o suficiente para postar mais de dois links, então aqui está a saída para /etc/apt/sources.list diretamente:

Com base no 6º erro da parte inferior da saída para apt-get update , parece que pelo menos um dos problemas é a incapacidade de autenticar algum pacote da Nvidia (provavelmente o repositório cuda que eu instalei de qualquer forma agora - foi que terrivelmente estúpido da minha parte fazer isso?).
Não sei o que fazer a seguir e gostaria de receber orientações. Agradecemos antecipadamente.
