The Iceland mirror has often been out of date and is now offline. Blame the maintainer/operator Siminn hf.
Unfortunately that is the only Ubuntu mirror in Iceland. Please try one of these up-to-date mirrors that should be close to you, network-wise:
You can change them from Software Sources in the Software Center, or press Alt+F2 and run gksudo software-properties-gtk, and see the below answer:
How can I get apt to use a mirror close to me, or choose a faster mirror?
This needs to be corrected. Síminn did not run the official Icelandic Ubuntu mirror. That was being run by LHÍ (Icelandic Academy of the Arts). They had trouble with it for a while.
Yesterday, a change to the DNS record for is.archive.ubuntu.com was made so now instead of pointing toward the LHÍ mirror it points to speglar.simnet.is which is in fact run by Síminn and has always been rock solid. So hopefully now the mirror will behave.
