I started getting an message box at boot and restart/shutdown saying:
Configuration file “/var/lib/sddm/.config/sddm-greaters” not writeable. Please contact your system administrator."
The message box only have a “OK”-button, and if I press it, everything seems to work as normal.
I have installed this update on both my stationary computer and on my laptop I have this issue only on my stationary computer. Which btw is fairly newly installed. Seems to be a pretty easy fix, but I does make me a bit curious why it started appearing.
