You could try deactivating the third party repos.

Ok, it's simple. First go to "System -> Administration -> Software Sources" from the main menu.

Then click on the "Other Software" tab, and un-check all the items listed.

I included some screen-shots to help.

i want to update my system NOT upgrade. what has been done to my sources list or whatever i do not know, but what i do know is the error i receive when i try to update

Ok then, here's how to fix those problems.

First open a terminal, then copy (ctrl + c) and paste (ctrl + shift + p) this:


sudo apt-get --yes --quiet --allow-unauthenticated install medibuntu-keyring

After, you'll want to go back to the software sources, and activate the main server. I attached a screenshot to help.

That's it! That should work! :)
