Update Manager error messages

[poldie]

Newish install of Mint 13 KDE, which has been working fine for a few weeks but now Update Manager is giving me errors. I've tried the UK mirror but no difference. I'm getting:

Failed to download http://packages.medibuntu.org/dists/precise/free/binary-i386/Packages
404 Not Found
Failed to download http://packages.medibuntu.org/dists/precise/non-free/binary-i386/Packages
404 Not Found

from Update Manager, and sudo apt-get update gives me (at the end of generally successful looking messages):

W: Failed to fetch http://packages.medibuntu.org/dists/precise/free/binary-i386/Packages 404 Not Found
W: Failed to fetch http://packages.medibuntu.org/dists/precise/non-free/binary-i386/Packages 404 Not Found
E: Some index files failed to download. They have been ignored, or old ones used instead.

It looks like this url is configured under Other Software in the:
http://packages.medibuntu.org/ precise free non-free
section. I can ping the url successfully.

Any ideas for what I should do here?

So... you can disable/delete the referring entries.

Ah! Many thanks!

So...every single Mint KDE user is going to get that error message? Seems a bit harsh!

If you go ahead and do the updates that do show up as available, there is one called "mintsources". I think that must fix the situation, as I did not have to manually remove the offending sources from my list. They just automagically disappeared.

Interesting. when I first tried Mint KDE, around a year or so ago, that was the first update, I think, and it made my machine hang. I had to seek help and I think ended up unlocking something and retrying and it fixed it. This time around it just installed fine, but clearly doesn't seem to have fixed this problem. Unless it was "mintupdate" I'm talking about. Whatever, I do regular updates and always take whatever's there.
