problems upgrading to kubuntu 20.04 (jammy)

[Martin van Es]

I had do-release-upgrade problems too, relating to my Wayland desktop
disappearing while upgrading and not giving me a tty to gracefully end the
upgrade.
Eventually I did get a tty and was able to wait for the upgrade process to
go silent (by inspecting top). So far my experience.
The advice: install and learn to use aptitude. I shows you the breaking
packages in red and you can quickly jump to them using the B key, offers
you solutions and you can inspect which package depends on what breaking
version. It has quite a steep learning curve, but once you know how it
works, it can help solving many dependency problems after upgrades.

Good luck!
