Do you have any PPAs installed ?
The upgrader will error out if you have any PPAs installed.

It seems to me that the Ubuntu/patches PPA is causing the problem.
I do not know what that is, but it is not part of standard Ubuntu

I suggest that you get rid of that PPA and revert to the "standard" updater-manager-core package (version 1:18.04.45 instead of version 1:18.04.45+Ubuntu1) and the same for other packages that you have installed from that PPA.

@Bernard,
 I do not have any ppas installed that I am aware of.

Manfred Hampl (m-hampl) said : 		#6

Your output shows that there are PPAs activated.

http://ppa.launchpad.net/Ubuntu/stable/ubuntu bionic/main
http://ppa.launchpad.net/Ubuntu/patches/ubuntu bionic/main
http://ppa.launchpad.net/Ubuntu/drivers/ubuntu bionic/main
http://ppa.launchpad.net/Ubuntu/apps/ubuntu bionic/main

If you do not even know about them, then you should disable them.

Oh my mistake. Yes there are ppas attached.I apologise for not admitting that right away. Should I disconnect those ppas?

Revision history for this message
Best Manfred Hampl (m-hampl) said : 		#8

It is not sufficient to just "disconnect those ppas".
Your output indicates that the packages than you have installed from these PPA cause the problems that you see, so you have to revert to the standard version of all software that you have installed from those PPAs.

thank you for this. This solved my problem. I love the quick response from Ubuntu tech support. Thanks!
