Falha ao baixar informações do repositório (entrada Wrong sources.list ou arquivo malformado)

Question

Eu recebo o seguinte log de erro ao tentar atualizar a lista de pacotes:

Failed to download repository information
Check your Internet connection.
W:Failed to fetch http://ftp.wcss.pl/ubuntu/dists/trusty-updates/InRelease  Unable to find expected entry 'main/binary-aarch64/Packages' in Release file (Wrong sources.list entry or malformed file)

E:Some index files failed to download. They have been ignored, or old ones used instead.

Tentei apt-get clean e autoclean , alterando servidores , mesmo removendo arquitetura (mas o dpkg disse que eu não posso porque está em uso pelo banco de dados). Também tentei remover a linha contendo as entradas problemáticas, mas o meu sources.list não as contém. Quando eu faço cat /etc/apt/sources.list /etc/apt/sources.list.d/* , é isso que eu recebo:

Isso também é diferente da duplicação sugerida - meu log de erros não contém um índice da linha corrompida. Na verdade, meu sources.list nem contém entradas semelhantes às mencionadas na mensagem.

O que posso fazer com isso?

    

Answer 1

De acordo com este erro:

 Unable to find expected entry 'main/binary-aarch64/Packages'

Você adicionou aarch64 architecture, mas os repositórios não têm pacotes para essa arquitetura.

Verifique:

dpkg --print-architecture

e

dpkg --print-foreign-architectures

Você deve ver aarch64 em arquiteturas estrangeiras. Remova-o:

dpkg --remove-architecture aarch64

Se você receber este erro:

error: cannot remove architecture 'aarch64' currently in use by the database

Você terá que remover qualquer pacote aarch64 que você tenha:

dpkg -l | grep aarch64

Remova tudo o que encontrar (com sudo apt remove )

E tente atualizar novamente.

Como alternativa, se você precisar desses pacotes , mantenha a arquitetura estrangeira e configure cada linha da sua lista de fontes que gera erros para pesquisar somente os pacotes das arquiteturas desejadas, adicionando [ arch=amd64 ] ou [ arch=i386,amd64 ] assim, por exemplo:

deb [ arch=amd64 ] http://archive.ubuntu.com/ubuntu/ trusty-updates main
