Description Andrei Rybak 2020-09-08 10:04:32 UTC

SUMMARY


STEPS TO REPRODUCE
1. Upgrade packages in `sudo aptitude` after 2020-09-08
2. Reboot
3. Try starting plasmashell from a tty


OBSERVED RESULT
- Plasma doesn't start after step 2.
- Undefined symbol from libQT5Quick.so error in tty

EXPECTED RESULT
- Plasma boots normally


ADDITIONAL INFORMATION
libqt5quick5 (version 5.14.2-0xneon+20.04+focal+build8) and 12 other packages are reported by aptitude as upgradeable, but trying to upgrade them leads to broken dependencies.  Solutions suggested by aptitude include removing neon-desktop package, unfortunately.

I have to type this from links in a tty, so getting additional info about KDE version is a bit hard.

I don't remember which edition of KDE Neon I'm using. I have the following in my sources.list:

$ grep neon /etc/apt/*.list
deb http://archive.neon.kde.org/release focal main

/release is a staging area for testing, please switch to /user which is the QAed archive

I'm afraid you'll probably now need to remove all qt and kf5 packages and reinstall to fix your system up

Thanks, Jonathan. Switching to

  deb http://archive.neon.kde.org/user focal main

helped.
