could not start kdeinit5 after Kubuntu upgrade to 18.04

Question

I wanted to update my kubuntu form 17.10 to 18.04 and i found this thread.

I used:

sudo update-manager -d

and it did something, but when I restarted only a black screen appears with the KDE PLASMA mouse cursor and a popup says:

could not start kdeinit5 check your installation

with an OK Button

What I tried so far: CTRL+ALT+F2 and login.

inxi -F says that is have Kubuntu 18.04. So that's what I wanted

sudo apt-get dist-upgrade

can't install libqt5xcbqpa5.

sudo apt-get --reinstall install plasma-desktop

any ideas?

Solution

it works again. i have this mesa ppa https://launchpad.net/~oibaf/+archive/ubuntu/graphics-drivers and before the update all 3rd party ppa get deactivated. i forgot about that. i just added the repository again and did "sudo apt-get dist-upgrade"

thx anyway

Also, when I first tried to upgrade a lot of software wasn't properly upgraded, so you might have to input a sudo apt update && sudo apt full-upgrade as well to resume installing those updates.
