Estou executando o ubuntu 14.10 no player VMware no meu escritório.
Sempre que eu tento adicionar um repositório, recebo esta exceção.
root@ubuntu:~# sudo add-apt-repository ppa:rvm/smplayer

Eu escolhi o smplayer apenas para testar o app-get. Consegui configurar o navegador para que eu possa conectar-me à Internet e fazer ping em algo como yahoo.com, mas não sei se há outras configurações de rede que estão faltando.
