I substituted kubuntu-18.04.3-desktop-amd64.iso for the ubuntu-mate-19.10-desktop-amd64, and made no other updates to the host.
This time it finished OK, however it produced only a 96MB .iso file, which unsurprisingly fails to boot with a "unable to find medium containing a live filesystem".
Logs attached.
Future tests I will do:
2) Apply your suggested Remedy for Issue #2 (A) or (B) to the current host, and run it against the original ubuntu-mate-19.10-desktop-amd64.iso
3) Try cubic on a new clean kubuntu-18.04.3-desktop-amd64 host against the ubuntu-mate-19.10-desktop-amd64.iso
If I understand you correctly, even though mate-19.10 is missing some files, because both Issues need to be present for this failure mode, the expectation is this should work.
4) Try cubic on a new clean kubuntu-18.04.3-desktop-amd64 host against the kubuntu-18.04.3-desktop-amd64.
Presumably, this should work.
Thank you.
I will do a series of tests.
Test 1)

Thanks for your help.
