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:

    Err http://archive.ubuntu.com/ubuntu/ raring-updates/main python3.3-minimal amd64 3.3.1-1ubuntu5.2

    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?

Change the APT download server. Open the Terminal and execute:

sudo software-properties-gtk

Form there, locate the downloader servers drop down list. Change your download server to, Main Server. Now do the upgrade again.
