You could try Linux Mint Debian Edition (LMDE) it has timeshift installed in the live iso, useful to restore a system when it’s unbootable. Anyway it doesn’t come with KDE but Cinnamon or XFCE.
For me Debian or LMDE is good for a home server due to not continuous package update, just major security an important ones.
For a Deskop or laptop in my opinion Fedora KDE or Gnome is the best experience.
May I ask what you’re using? Which distro?
Just found it and tried on my home server, it works:
version: '3.3'
services:
yarr:
container_name: yarr
image: maskalicz/yarr:latest
ports:
- 7070:7070
volumes:
- ./yarr-data:/data:rw
Anyway, it just have one view mode with 3 panels and it’s not customizable. At the moment, the most featured and exstesible RSS Feed service seems to be FreshRSS as suggested in the thread by @specseaweed@lemmy.world.
