Hi,

i have the same error. I tried to release upgrade with: sudo do-release-upgrade -d

Last messages from my dist-upgrade/main.log file:

I have the same problem when trying to upgrade to 20.04 from 18.04
colord reported as a broken package
I purged colord and ubuntu-desktop but still colord reported as a broken package in the main.log file.

[Gabor Csejtey (csgz2)]

Success ?!?!?!

After trying to upgrade several times it started just now to upgrade.

I reinstalled packages reported as broken in api.log and enabled previously disabled ppa for previous upgrade from 16.04 to 18.04.

Reviewing the files from your upgrade attempt you seem to have enabled a PPA that provides Xorg and python packages. This will prevent the upgrade as that PPA contains packages which generate failures when trying to calculate the upgrade. You can revert the PPA by installing the ppa-purge package from the official Ubuntu archive and then running 'sudo ppa-purge ppa:oibaf/graphics-drivers'. After that you can try upgrading again and if it still fails open a new bug report. Thanks and good luck!
