I am trying to install ubuntu server 12.04 LTS and there is a screen that comes up during the setup called "Configure the Package manager":
If you need to use a HTTP proxy to access the outside world, enter the proxy information here. Otherwise, leave this blank.
The proxy information should be given in the standard form of "http://[[user]@[:pass]@]host[:port]/".
HTTP proxy information (blank for none):
I am not sure if "I need to use a HTTP proxy to access the outside world". How do I know?
EDIT
I am planning to use nginx as proxy to jetty, does this setup refers to that?
