For some reason, apt-get upgrade isn't working today. This is what I see when I try to upgrade :

root@localhost:~# apt-get upgrade

E: Unable to fetch some archives, maybe run apt-get update or try with --fix-missing?

Any idea what went wrong or how to fix it?

Thanks for taking a look!

Have you tried apt-get update before the upgrade ? –  krisFR Mar 18 '14 at 18:40
Okay, looks like I should have just followed directions to begin with. I ran : apt-get upgrade --fix-missing . It executed without issue. I rand apt-get upgrade a couple more times until there was nothing left to update. However, when I run apt-get update, I still get 403 "Failed to fetch" errors when trying to contact us.archive.ubuntu.com/ubuntu/dists/precise-backports . Any idea what's going on here? –  sangfroid Mar 18 '14 at 18:50
What happens if you manually try to grab one of those packages? Are you behind any sort of weird firewall or similar? –  devicenull Mar 19 '14 at 2:41
