Just remembered looking into caching updates so my other PC could access the updates from this LapTop rather than getting them from the internet again. Can't remember exactly what I altered in this LapTop though.. I actually thought I removed / undid all I had tried. BTW, the caching never saw the light of day.. Maybe this will give you a clue where to look?

Ohh, now we're getting somewhere. This type of setup can be achieved using a proxy. I think you need to try to dig back through what you did. Did you follow some tutorial somewhere? Perhaps you installed some package. Try checking your /var/log/aptitude and/or /var/log/apt/history* etc.

Cheers,

This is from one history file..

Start-Date: 2013-12-24 13:55:06

Start-Date: 2013-12-24 14:04:02

Hi,

it is almost certainly related to the installation of apt-cacher-ng. In my first post I asked if there was a proxy set in /etc/apt/apt.conf, can you please double check that there is not?

Evo2.

PS. I see now that I made a mistake in my first post, it should have been /etc/apt/apt.conf not /etc/apt.conf

This line is in a file under /etc/apt/apt.conf/01proxy

Acquire::http::Proxy "http://hostname:3142";

Hope this is the problem..

Bingo.

Presumably the path is actually

Code:

/etc/apt/apt.conf.d/01proxy

But anyway that's the cause of your problems. Delete that file and your package managers should start working again. Alternatively, purging apt-proxy-ng may delete that file for you.

Eg.

Code:

sudo apt-get purge apt-cacher-ng

Glad to hear it. Did you manually delete the file or did you purge the apt-cacher-ng package?
