what is the problem??

I am on vpn on host pc, but setting up proxy on guest should work fine right?
While Installing ubuntu in virtual box there is a "NAT" networking configuration.

All what I want is host is connected to vpn and for guest I want to use command line to install packages use torrent to download stuff is this really possible?

It looks like your proxy still might not be set up correctly:

Add these lines to ~/.bashrc replace your variables where necessary.
Then reload your bashrc
