The maintainer probably deleted them. If you go to http://ppa.launchpad.net then you'll see a directory listing for other repositories. I get a 404 error as well.

Well that is uninformative.

What about the rest of your repos? Did they all update right?

Why are you getting 32bit and 64bit packages.

Is that the correct entry for the ppa? Did you add it by following the instruction on the ppa web page?

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?

uhkilleez 11-02-2012 12:57 PM

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? :)

uhkilleez 11-02-2012 03:45 PM

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.

I find this discussion very helpful when I have questions/concerns about Ubuntu security: http://ubuntuforums.org/showthread.php?t=510812

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).

I am not even fond of Ubuntu or their "security model" but that ppa was not installed by some mysterious force.

Run;
Code:

sudo ppa-purge
and that should clean it out and set your computer back to the packages and configuration that it had without the ppa and any possibly installed packages from it.

To calm your nerves a bit I can say that while I never ran that ppa myself I know people that used it and it has a good reputation.

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.
