MusicBrainz Picard v2.1.0 snap is now in the beta channel for amd64 arch:
sudo snap install picard --channel=beta
If you’re a user of the application or even if you just want to poke at it, I’d love some help putting it through its paces! Please let me know if you run into any issues.
The only know issue right now is that the language selection does not work, but we are trying to solve it: https://tickets.metabrainz.org/browse/PICARD-1398
