Stopping the service before the purge fixes the problem.
This is the expected output when sddm is still running. We don't want to stop the running display manager as it will kill the graphical user session.

This part is not caused by us. Mmh, after a closer inspection this is caused by the debconf purge, which get's confused with any message written to stdout.
I'm cloning the issue to debconf, as it would be better if db_purge wouldn't be trying to parse whatever was printed to the stdout.
On the sddm usecase, I'll add the deluser and echo redirections (>&2). Happy hacking, -- A computer scientist is someone who, when told to "Go to Hell," sees the "go to," rather than the destination, as harmful. Saludos /\/\ /\ >< `/
