Original sources.list do Ubuntu 15.04 Google Cloud Compute VM instance

Question

Eu acidentalmente excluí o arquivo sources.list da minha VM do Ubuntu em execução em uma instância do Google Compute Engine.

Como Amazon Web Services, eles também têm seu próprio sources.list otimizado. Eu preciso de um original não modificado, por favor.

UPDATE: De acordo com a resposta de JakeGould , deve haver um backup do sources.list no /etc/apt/ chamado sources.list.save , mas eu verifiquei não encontrei o arquivo na minha instalação:

$ ls -la
total 64 
drwxr-xr-x 6 root root 4096 Sep 17 21:06 .
drwxr-xr-x 100 root root 4096 Sep 17 21:22 ..
drwxr-xr-x 2 root root 4096 Sep 9 06:54 apt.conf.d
drwxr-xr-x 2 root root 4096 Apr 7 14:44 preferences.d

Answer 2

Não há necessidade de construir uma configuração completa do Ubuntu apenas para obter uma cópia limpa do sources.list . Basta procurar no diretório /etc/apt/ :

ls -la /etc/apt/

Deve haver um sources.list.save nesse diretório que é basicamente um backup simples lado-a-lado do sources.list original em seu sistema. É claro que quaisquer modificações / ajustes que você tenha feito serão eliminados. Mas ei! É melhor que nada. Basta copiar o arquivo no lugar assim:

sudo cp /etc/apt/sources.list.save /etc/apt/sources.list

E você deve ser bom para ir.
