I installed Debian on my wife's new computer mainly because I am running Debian and I figured I would keep it all the same. Only problem is I can't get Netflix desktop app to work. I tried following this:

http://www.skybert.net/debian/netfli...-wheezy-64bit/

I get various errors when running apt-get update so it seems maybe some repositories are out of date or don't exist anymore? I had this running on her old computer with Mint 16. She can't live without Netflix. Are there any ways to get it running on Debian Wheezy right now? I don't want to re install her computer if I don't have to

The devil is in the details. Statements like "I get various errors when running apt-get update so it seems maybe some repositories are out of date or don't exist anymore?" are vague and not at all helpful. What errors? What commands provoked the errors? and so on. I'd suggest you try again and make note of all the steps you took and all the consequences of those steps.

Apart from the Netflix issue, is Wheezy running correctly?

Well, wife had a Win7 license with her computer so I just installed it on VirtualBox. Not the best solution but Netflix/Chrome run surprisingly well inside the VM. If you skip ahead or back it takes a few seconds to buffer but playback is as good as running it native. And my wife watches it in a small broswer window while she does research and school work on her computer so it's fine for her needs.

I'm very pleased to hear that. Is there a question?

The reason Skybert's tutorial failed is Ubuntu Oneiric reached its "end of life" a year ago and is no longer supported:

My advice as someone who spends a lot of time on Linux forums is: always follow up-to-date tutorials from trusted sources.

The two projects I know of that bring Netflix to Linux are netflix-desktop and pipelight. I recommend that you go straight to the official sites for accurate information (rather than some random guy's outdated blog):

I watch netflix everynight on my Linux boxes with pipelight.

Depending on how you did the install you can have apt issues.

# apt-get install dselect

# dpkg --clear-avail
# dselect update

Should build a fresh available archive and merge multiple sources into a single list. AKA dpkg-query --load-avail -l '*something*' will actually get results. I have to do the above when I do a debootstrap install. And the dselect line if I make changes to /etc/apt/sources.list.
