I am currently at a conference in another country and my package manager cannot access repositories. My internet is working fine and I can ping the repositories or go to them in a browser, but package manager fails to access them. If I sudo apt-get update it throws

Something wicked happened resolving 'wwwproxy:3128' (-5 - No address associated with hostname)

(or Ign's). This proxy corresponds to my proxy at my office back at home, but I have disabled proxy in the package manager.

Scanning for best repository doesn't work either, it doesn't manage to connect to any.

I have searched for this online and have checked things about my apt.conf file. My apt.conf contains:

Acquire::http::proxy "http://wwwproxy:3128/";
Acquire::https::proxy "https://wwwproxy:3128/";
Acquire::ftp::proxy "ftp://wwwproxy:3128/";
Acquire::socks::proxy "socks://wwwproxy:3128/";

If I remove apt.conf (or replace with blank), it makes no difference. I don't see that it should since I am connecting directly (and have set it so in my network options in Package manager network settings)

I have also tried some things with resolv.conf (changing name address to primary and secondary dns) to no avail. (im not sure if this would help, following other advice)

I am running 12.04.

(I wrote this very quickly and wrote down everything I have tried to possibly shorten the troubleshooting process, have very limited time between lectures and need this sorted asap, my apologies)
