It seems duplicate but really it's not, I'm really tired of testing all solutions and reaching no success. even I'm thinking about going back to windows because I had several problems with Ubuntu 12.04 .

When I type sudo apt-get update

0% [Waiting for headers]

appear and stick at this percent and sometimes it goes up to 15 or 30 or ...
I change my server from sources.list and also I chose best server from update manager and even pick software update's checkbox tick but eventually no change to my problem.

Do you have any idea to fix it? I can't wait anymore. thanks in advance

  • It seems like the "best server" is not a very good server. Perhaps you can try another server?

  • @Rinzwind few days ago I tried to install squid but because I didn't know and didn't understand how to configure and use it correctly I did sodu apt-get remove squid. is that correct? and finally I don't think so that I'm behind proxy
