It’s not exactly easy, but usdb.animux.de still works. They provide a Youtube video on which the notation is based, and offer the notation/lyrics txt file for download. You do have to make an account, though.

Alternatively there’s Nightingale, which seems to be similar to USDX. You can just point it to your music collection, and it grabs lyrics, determines the pitch, and even separates vocals from instrumentals with AI - though it takes quite a while, and doesn’t support AMD cards, which is why I haven’t tried it myself.

I also have a large USDX collection I’d be willing to share. DM me if you are interested.

EDIT: I just found UltraSinger, which also automatically generates USDX txt files from music.

I managed to fix the same problem by installing avahi and nss-mdns.

sudo apt install -y avahi-daemon avahi-utils libnss-mdns

Should do the trick on Ubuntu.
