Qual é o problema? (eu estou usando o Ubuntu DISTRIB_RELEASE = 14.04)

    

Answer 1

Uma simples pergunta recorrente no lugar errado para fornecer uma resposta detalhada tem uma solução simples, neste caso duas delas desde que você recebeu dois tipos diferentes de mensagens de erro padronizadas.

1. Remova os PPAs que não existem mais nas suas fontes de software. No Dash, selecione Software & Atualizações e, em seguida, a guia Outro Software - > remova todas as fontes de software PPA que não existem mais, desmarcando-as. As fontes de software que você precisa remover são aquelas que causaram a você as mensagens de erro 404 Not Found ao executar sudo apt-get update .

2. Você também tem uma linha malformada em suas fontes de software. Remova essa linha manualmente de /etc/apt/sources.list seguindo as instruções em Como removo uma linha malformada da minha sources.list? .

Answer 2

Tente esta resposta :

Evidentemente, o apt não consegue lidar com muitas fontes de software, por isso pude resolver o meu problema, desmarcando tudo, exceto o que eu precisava acessar. Isso seria uma dor real para fazer com freqüência, mas é melhor que nada. Do site:

From the "Other Software" tab, disable all PPA repositories, leaving only the official Ubuntu repositories active. Enabling too many PPA repositories (which are non-official) can cause your package manager to become unstable.
