You have plenty of broken packages: clean your system and downgrade to genuine versions (via ppa-purge)

@dino99, your reply is not helpful, which packages from which PPAs are you talking about?

[dino99 (9d9)]

At first glance, these 2 'extra' sources could have introduced some conflicts:

I cannot reproduce the issue with the clone. But from the look of it I am wondering if some leftover from xenial could be causing this problem.

[ben_31 (benoit-maricau)]

The problem was solved by removing some conflicting packages:
- libavfilter6,
- libopencv-highgui3.1,

and then "apt autoremove".

[Jean-Baptiste Lallement (jibel)]

Right but they are both official versions and shouldn't block the upgrade.

[Brian Murray (brian-murray)]

Looking closely at the Aptclonesystemstate file we can see that the installed version of libavfilter6 was actually the bionic version installed on artful.

 686 libavcodec57 7:3.3.4-2 1
 687 libavfilter6 7:3.3.4-2 1
 688 libavformat57 7:3.3.4-2 1
 689 libavresample3 7:3.3.4-2 1
 690 libavutil55 7:3.3.4-2 1

This certainly caused the failure to calculate the upgrade and is not something we can fix.

[Brian Murray (brian-murray)]

Sorry I misread the version numbers. This is actually the version from 17.10.

[Brian Murray (brian-murray)]

I installed libavfilter6 and libopencv-highgui3.1 and was not able to recreate the bug so there must be some more packages involved.
