The upgrade went well until the reboot. First of all, SDDM didn't display the theme and an error message in red indicating that it couldn't find a file. I logged into TTY and searched for and installed the missing RPMs, which are not installed by default: - libQt6QuickLayouts6 - libQt6Xml6 - libQt6Svg6 From there SDDM displays the theme. By entering login + password, there is a connection attempt then back to Greeter with Wayland as X11. In TTY , I found that libQt6Core5Compat6 was missing for wayland. I was able to launch a plasma 6 session under wayland with an ugly display that didn't respect the theme colours, among other oddities. However, with X11 I get a black screen for SDDM. So I can't connect. So reboot + snapper rollback to plasma 5 for now. I attach the upgrade history for information. -- You are receiving this mail because: You are on the CC list for the bug.
