My 10.11 migration blew up because one of my directories didn’t have enough space for the migration.
The path
/var/lib/jellyfin/datahas insufficient free space. Required: at least 2GB.
It looked like the jellyfin service started after the package install, but it was stuck in a loop attempting migration.



I tried XFCE for some older hardware and had the same experience.
I poked around at stuff like fluxbox and found it too minimal. So I ended up using LXDE instead and got better results, but that was before it transitioned to LXQt. I have no idea if it’s still as lightweight as it used to be. Someone else might have to chime in.
