I have Ubuntu 13.04 Server on a Virtual Box which is using 2GB of ram and 20GB of space. It's freshly installed and I cannot use apt-get update.

I have tried the same on an Ubuntu 12.10 Server but it still doesn't work.

Every time I type apt-get update I get

0% [Connecting to ca.archive.ubuntu.com (91.189.92.202)] [Connecting to security.ubuntu.com (91.189.91.15)]

Which then hangs for about 20 minutes, and then this displays

Err http://security.ubuntu.com raring-security Release.gpg

W: Some index files failed to download. They have been ignored, or old ones used instead.

However I can ping the IP address and domain on the server, and I can access it on my Host machine browser

I have tried restarting my computer, reinstalling my Virtual Machine, restarting my router many times, modifying the sources.list, and I have been googling for several hours, and can't figure out why it's not working.

I have also attempted to disable IPv6 (http://www.bearfruit.org/2013/05/06/ubuntu-server-having-ipv6-probs-its-easy-to-disable/)

Last night I had setup an Ubuntu Server to test it out, and apt-get update worked last night. Now, it's not working anymore on a new Virtual Machine. The one I created yesterday was deleted, and the new one I created today is not working.

My host machine is a laptop and I am using wifi, the specs of it is

Windows 7

8GB Ram

658 GB HDD (214 GB used)

AMD A8-3520M APU

Edit: I am not behind a proxy/vpn, and my internet connection is fine.
