CrunchBang Linux

Okay guys, here's the fix. I had this problem myself, and fixed it by changing two files.

First:
sudo nano /etc/apt/apt.conf

Then delete (or edit) the contents of the file and ctrl+x to exit, then 'y' to save.

Then:
sudo nano /etc/profile.d/proxy.sh

And again, delete or edit the contents, ctrl+x to exit, 'y' to save.

Hope this helps!
Will.
