Quick and simple to do command line apt:
System-wide proxy set up:
If you have to use a proxy then you can set it up system-wide here:
Make some changes to /etc/profile just before the following line:
export PATH USER LOGNAME MAIL HOSTNAME HISTSIZE INPUTRC
When you’re done it will look like this:
http_proxy=http://proxy.mydomain.com:8080
https_proxy=https://proxy.mydomain.com:8080
export PATH USER LOGNAME MAIL HOSTNAME HISTSIZE INPUTRC http_proxy https_proxy
(I’ve bolded the changes so you’ll see which lines to add)
