I had this trying to upgrade from 14.04 to 14.10, although I didn't get
any indication of the package causing the problem - see #1406740.
I tried commenting out the postgresql line from removal_blacklist.cfg,
like cfi mentioned, but similarly it didn't fix the problem for me.
Once I removed all
Public bug reported:
I ran the software updater and then chose to upgrade to 14.10. I'm on
14.04.
During the Setting new software channels step I get an information
dialog that:
Third party sources disabled
Some third party entries in your sources.list were disabled. You can re-
enable them
After filing this I spotted the no entry icon in the system
notifications by the date/time in the top-right corner of the screen.
It would be handy if the dialog had pointed towards this, as that seems
to show the details of the offending package.
I removed wine, which got a little further before
