I guess I will have to do the experiment on another hardware platform to sort that out.
OK, a second d-u experience to report, on my main desktop rig. This one was longer and considerably more difficult, but in the end it is fully upgraded and running a Plasma 5 desktop with no apparent problems. Here are the highlights:
- at a point very early in the process the configuration of an updated new udev package hung with a "connection timed out" error. I lost a lot of time trying different apt and dpkg commands to make it proceed before I discovered that systemctl could not tell me anything about my system, nor could it shut my system down. So there was a major systemd malfunction and there was no way to proceed except to press the reset button, boot a live USB stick and run gparted to check my filesystems, and try a reboot. It came up all the way to a Plasma 5 desktop which was fairly amazing. I went back to tty1 and continued the d-u.
- later in the d-u after the big removals, kde-standard, dolphin, and plasma-desktop refused to install or update. It took a lot dependency chasing and comparisons to my updated Dell laptop to figure out that phonon4qt5 was at the heart of the problem. I installed phonon4qt5-backend-gstreamer and then the others installed including libreoffice. phonon4qt5-backend-vlc appears to be uninstallable at this moment. Also don't forget to install systemsettings -- it disappeared during the process and had to be reinstalled.
- the final reboot brought me to a clean default Plasma 5 breeze desktop. At first I thought was a different behavior than I had on the laptop, but then I realized I had never customized the desktop on the laptop. Probably it overwrote the old desktop and I did not notice a difference. But my big rig was highly customized with a slideshow that used webcam images and a desktop cube and login music, so all that has to be redone.
