Package Manager cannot access repositories but internet is working

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)

Clearly apt-get (and Synaptic) think there's a non-existent proxy set somewhere.

Try forcing a one-time no proxy with the -o option, for example:

 sudo apt-get -o Acquire::http::proxy=null update

and see if that works.

If it does, you can use it for any "emergency" updates/installs.

Note that the apt.conf file is obsolete and settings are currently stored in multiple files under /etc/apt/apt.conf.d/. To solve this problem, run grep -r Acquire /etc/apt/apt.conf.d/* and paste the output here so we can help you further.
