Introduction to Linux - A Hands on Guide
This guide was created as an overview of the Linux Operating System, geared toward new users as an exploration tour and getting started guide, with exercises at the end of each chapter.
For more advanced trainees it can be a desktop reference, and a collection of the base knowledge needed to proceed with system and network administration. This book contains many real life examples derived from the author's experience as a Linux system and network administrator, trainer and consultant. They hope these examples will help you to get a better understanding of the Linux system and that you feel encouraged to try out things on your own.

These are 3rd party software sources not provided or supported by Canonical that YOU added to the system for some reason, so why did you add them, and have you gone back to the website where you found them to get more information/details?
I didn't ever add anything at all. If they are third party sources, I don't know why they are there. I'm not sure why I am getting 32bit packages as well as 64 bit, I am running a 64bit version of ubuntu.
EDIT: I found the ppa entries and unchecked them in the update settings. It's fixed the updating issues. Any ideas on where they came from? I did NOT manually add these.
If your important system files are randomly changing without you doing anything, and you are the only person with access to the computer, then I suppose it is possible you have a virus. However I have never even heard of a Linux virus, so the more likely explanation is that you installed something a while back and forgot you did it?
To be blunt, the biggest security threat to any operating system is the user. If you are installing software from untrusted sources without paying attention or keeping a record of the changes you've made, then that's your responsibility (and not the makers of Ubuntu).
It's very possible that something which I've installed may have made the changes. I honestly haven't paid all the much attention to that particular issue.
As snowpine said, those PPA repos are unsupported by Ubuntu; you add them at your own risk.
I have seen a great many threads around here with all kinds of problems that ultimately were caused by rogue third party repositories, including those PPA repos.
Anyone at all can create a PPA repo for Ubuntu and add it to the Ubuntu PPA website. There are no special skills that are required, and no standards that must be met.
So the quality of those PPA packages varies greatly.
For the most trouble free Ubuntu experience, avoid all third party repositories. If you must use third party repositories, use them sparingly, and at your own risk, and only if there is no other suitable option available in the standard Ubuntu repos.
