Quando tento instalar um novo software por meio do terminal, como:
sudo apt-get install nethogs
Eu recebo o seguinte erro:
E: Unable to fetch some archives, maybe run apt-get update or try with --fix-missing?
Quando tento usar o argumento --fix-missing após apt-get , ele mostrou que não foi possível buscar as fontes.
Quando uso sudo apt-get update , não consigo reunir fontes de software e muitas delas são ignoradas e apresentam erros.

Eu li o tópico this . Eu removi ubuntu-extras-keyring , mas não consegui instalá-lo novamente.
Eu acho que pode ser um problema com a minha conexão com a internet, mas quando eu faço ping 4.2.2.4 ele funciona corretamente e eu posso navegar na internet sem nenhum problema.
Não consigo instalar nenhum software nem atualizar fontes de software.
Baixe ubuntu-extras-keyring e depois instale-o. De:
Em seguida, altere o espelho de download (consulte Download From: lista suspensa), usando:
sudo software-properties-gtk
Como mencionado na resposta com votos mais altos, 'Alguns arquivos de índice não conseguiram baixar' durante a atualização
