When I'm trying to enable some sources in Other Software in Software Sources I see an auth prompt, but when I put in my password, I see no changes of checkboxes states. What can I do to fix this?

Open your terminal and type

sudo -H nautilus /etc/apt/sources.list.d/

Delete all files that have an extension .DistUpgrade

Rename .list and .list.save files by changing the older release name(precise) to the new one(quantal)

This solved it for me.
