If I well understood you, what you want is Debian with a great intaller. Don’t search anymore, there is the great Spiral Linux! Enjoy it.

This is an intuitive PDF page editor for linux: Pdfmixtool

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?

I think the best approach is: search, try and stick with games you enjoy the most 🙂

Stability and configuration options. I already used Jellyfin but for me is not stable. It often crashes and configuration options are a mess at the moment.

Considering that I’m using Emby (selfhost), it’s able to manage my music collection too and I can play the music from the web player exposed by it.

If you want a desktop distro up to date with kernel, DE, etc. which does’t crash I can advice Fedora. Aftet the six month release cycle it is easy to update. I used it for a couple of years on my home pc and it was very good.
