Sometimes it just don’t find the audio fingerprint. Try the lookup button instead. Or fill in the missing info by hand. Btw I usually use the --embed-metadata flag on yt-dlp. Most tags should fit like that.

I use NginX Proxy Manager gor my homelab. For my business setups I use Traefik.

Sounds like a good idea! I read somewhere, that you can also launch Docker via Termux on Android. Just in case Postmarket OS won’t work.

If you want to compleetly start over you can write a new partition table. I usually boot a gparted live disk and prepare my partitions there.

For old PCs I can recommend Linux Mint. It’s easy to use and low on ressources.
