I came across this problem when I was setting up a new box with Linux Mint 13 Cinnamon (64-bit). This machine lives in a corporate type environment and needs to have a proxy configured to have internet access so I suspect that some incorrect proxy settings could’ve caused this scenario.
Here’s the output (with boring bits removed) that I got from running
sudo apt-get update:

You’ll notice the second to last line speaks about a local path, which made me think that the issue is with some data that we’ve cached locally and it’s not being overwritten with fresh stuff.
The fix is to delete (or rename) the cached data that apt keeps so it’ll refresh everything. I found there’s two locations that needed to be deleted/renamed:
sudo apt-get update to get fresh copies of all the indexes, etc.
You should be good to go :D
