Não instalar softwares depois de mudar o servidor

Question

Mudei o servidor de download do servidor sri lanka para o servidor dos EUA usando o software e a janela de atualização. Então eu tentei instalar o mysql usando este comando.

sudo apt-get update
sudo apt-get install mysql-server

Isso me dá esse erro.

Reading package lists... Done
Building dependency tree       
Reading state information... Done
N: Ignoring file 'google-talkplugin.listsudo' in directory '/etc/apt/sources.list.d/' as it has an invalid filename extension
N: Ignoring file 'google-talkplugin.listsudo' in directory '/etc/apt/sources.list.d/' as it has an invalid filename extension
E: Unable to locate package mysql-server

Então eu tentei mudar o servidor de download de volta para o servidor sri lanka. Mas esse servidor desapareceu nos locais dos servidores. Quando clico no botão "selecionar o melhor servidor", ele diz

No suitable download server was found. Please check your internet connection.

Como posso resolver este problema?

    

Answer 1

Você pode editar o arquivo /etc/apt/sources.list manualmente. A partir daí, você pode alterar todos os servidores de volta para o link . Na minha área de trabalho, isso é listado como o espelho do Sri Lanka. Você pode usar gedit, nano, leafpad, vi ou seu editor de texto favorito para abrir o arquivo com permissões sudo. Exemplo:

sudo gedit /etc/apt/sources.list

O arquivo deve ser parecido com isto ou aproximadamente semelhante com base nas preferências individuais do usuário.
