First off, I recommend updating to at least 14.04 LTS, as there's no reason to install an old LTS while there's a better one.
Netflix on Linux is only supported in Chrome, not Chromium, not any other browser claiming to be Chrome either.
You should download the Ubuntu version of Chrome directly from it's website: https://www.google.com/chrome/browser/desktop/index.html. Once installed, everything should work out of the box.
If you get any missing dependency problems while installing Chrome, attempt to install each package by sudo apt-get install <package>
, if it can't locate the package, it may be that a required library is only available on a newer version of Ubuntu.
In such a case, I know for a fact that Netflix works on 14.04 LTS, 14.10, and 15.04 using Chrome 43.
If you get the [broken chache]
issue when installing the package, you should issue a few commands to clean up your install environment:
sudo apt-get clean
sudo apt-get update
sudo apt-get install -f
sudo apt-get upgrade
That should purge all caches, install missing dependencies, then upgrade old packages in that order.
