Eu tenho uma instalação limpa do Ubuntu 16.04 LTS, mas como minha máquina está rodando atrás de um firewall / proxy corporativo, não posso descobrir como superar os obstáculos. Eu sei que temos um proxy corporativo, e eu tenho o servidor / porta / nome de usuário / senha para usá-lo, mas eu não sei se isso vai resolver o meu problema inicialmente. Provavelmente, ainda precisarei adicionar a origem do pacote à nossa lista de endereços IP da lista branca.
para começar, aqui estão as mensagens de erro que estou recebendo ao tentar instalar quaisquer pacotes.
sudo apt install software-center

Package software-center is not available, but is referred to by another package.
This may mean that the package is missing, has been obsoleted, or is only available from another source
E: Package 'software-center' has no installation candidates
onde começo a desatar o nó que minha empresa fez?

Para configuração de proxy temporário ... quero dizer apenas para a sessão atual, execute o comando abaixo:
export http_proxy=http://yourproxyaddress:proxyport
Para adicionar esta configuração de proxy permanentemente, edite o arquivo apt.conf
gksudo gedit /etc/apt/apt.conf
E adicione a linha abaixo:
Acquire::http::Proxy "http://yourproxyaddress:proxyport";
