....... até que eu parei.
também o sistema configurações- > detalhes mostra que isso é 14.04LTS
saída de:
dpkg --print-architecture
é amd64
eu abri o arquivo /etc/apt/sources.list e não há menção de utópico. em todos os lugares é confiável.
[Update - 2]
Eu verifiquei os links acima e não há realmente nenhuma entrada de main/binary-amd-64/Packages , mas em todos os lugares é main/binary-amd64/Packages (observe o hífen entre amd e 64).
eu usei o comando:
grep -r "amd-64" /etc/apt
e não obteve saída.
