When I run sudo apt-get update I receive the following error message:
W:Failed to fetch http://http.us.debian.org/debian/dists/squeeze/Release
Unable to find expected entry 'universe/binary-amd64/Packages' in Release file (Wrong sources.list entry or malformed file)
E:Some index files failed to download. They have been ignored, or old ones used instead.
Can anyone help?
The best way I have found of solving most problems with "failed to fetch" is to check that you are using the best server. The reason this works is that in the process of selecting the best server it has to ping each of the available servers to find the one that responds the fastest. If there is anything wrong at your end the entire process would probably fail otherwise it my select a different server if the one you normally use is down for maintenance. I personally do this as one of those "after Installation todo's"
Hope this helps.
It sounds like you've run dpkg --add-architecture 1386 at some point. If dpkg --print-foreign-architectures shows 1386, running dpkg --remove-architecture 1386 should fix the problem.

You certainly should not mix Debian and Ubuntu repositories. Some of the packages in either one of them will have different depends.
The fact that Ubuntu derives from Debian does not mean you can mix the repositories. This usually fails.
