Upgrade 18.04->20.04 gone pretty badly

[udippel]

(I wonder: should I do individual messages, or write down everything in one go? - This is no bug report, so I give it a single go:)

0. I didn't want to upgrade. I only had a standard daily apt-get with 'dist-upgrade' working; which at any moment in the past didn't actually do that; I simply had applied that for convenience: It wouldn't ask for additional packages. Yesterday, there wasn't even a question popped up, if I really wanted to upgrade to 20.04; bang, 'apt-get dist-upgrade' and there it was. Over.

1. It used to be a dual boot with W10 before, after the upgrade, it is just a (k)ubuntu 20.04. No more grub selection menu.
-> (Remains unsolved, though:) I checked the BIOS (lenovo Helix 2), and found the ubuntu drive as first boot device, Windows boot loader second, and so forth. So it seems to correctly point to the correct device, I guess. So I can boot to W10 by selecting temporarily the W10 boot loader.

2. Touchpad didn't do the double-tap any longer; had to tap + left mouse button. Solved by finally finding a solution: editing /usr/share/X11/xorg.conf.d/40-libinput.conf

3. I had a left edge mouseover leading to the 'show desktop' which is still set, but doesn't work any longer.
-> This one I could solve: The compositor was disabled (NOT by me!); and System Settings->Display and Monitor->Compositor>Enable could solve this matter with a reboot.

4. The speakers in my tablet are 'dead'. They are visible, but produce nothing.

That's it what I encountered until now.
I'd be most happy to hear solutions for 1,3 and 4.

Kind regards,

Uwe

I don't understand how running that dist-upgrade command managed to move you from 18.04 to 20.04, though I am aware that the option in the update manager has only recently appeared, a bit later than usual.

Can you double check that you're now on focal and show us your active repos with command
cat /etc/apt/sources.list

Sure, here is what it looks like now:


$ cat /etc/apt/sources.list

I DID try the sudo do-release-upgrade -m desktop a number of times in the past; just to SEE if the update was finally available. I was willing to update, but not in this moment of time, while I am very busy with my lecturing tasks. A number of times it failed, last time it did something; but I Ctrl-C it out immediately as I knew it would be ready by then. Any background job keeping running?
In any case, I'd expect to be asked at least once "Are you sure ...?" Before, it had also informed me about commenting out certain third party software and stuff. Yesterday sudo apt-get dist-upgrade just downloaded 2300+ packages, done.

You either need to manually edit the /etc/apt/sources.list file, removing the # at the start of all lines beginning # deb-src or, quicker and simpler for most users, enable source repos in the software sources application.

... last time it did something; but I Ctrl-C it out immediately as I knew it would be ready by then. ...

That explains it. do-release-upgrade changed the software sources to focal and began calculating the upgrade, then you killed it with ctrl-c but didn't restore the original software sources from backup. So the next time you ran apt-get, it checked the focal repositories and performed the release upgrade.
