apt-get upgrade gives "403 forbidden" error
- by 3l4ng
I'm running Ubuntu 13.04 64b.
sudo apt-get update works fine, but when I run sudo apt-get upgrade I get these errors:

E: Unable to fetch some archives, maybe run apt-get update or try with --fix-missing?
Running sudo apt-get upgrade --fix-missing installs some updates, but the above errors still persist when I run apt-get upgrade again.
The software update app shows the error: https://www.dropbox.com/s/2cr450557hmahzz/software_update.jpg and selecting continue shows: https://www.dropbox.com/s/l7u32sxyfbxxeeg/soft_upd2.jpg (sorry for the links, I don't have enough rep to post images)
I am behind a proxy, but apt-get update and web browsing work without issues. I also do not believe a server being down is causing this, as the problem has been there over a month.
Any ideas on how to fix this?
