Original title: Не могу обновить или установить пакеты Ubuntu server 18.04
Can't update or install packages on Ubuntu server 18.04. Internet provider Rostelecom, we sit behind their proxy server and content filtering. And so that we could work normally with Ubuntu server 18.04, they ask us to provide update ports. sources.list
is not enough for them. Where can I see the list of ports??? Thank you in advance! Regards, Oleg.
