I am running mopidy 2.3.1 and Iris on raspbian buster. It support python 3.7.4 but I suppose I can’t update to mopidy v.3 as long as Iris doesn’t switch to python 3.
Should I “pin” all mopidy and plugin packages to keep them at current version?
```
ii libspotify12 12.1.103-0mopidy1 armhf Library for using the Spotify music streaming service
ii mopidy 2.3.1-1 all music server with support for MPD/HTTP clients
ii mopidy-alsamixer 1.1.1-1 all Mopidy extension for extension for ALSA volume control
ii mopidy-internetarchive 2.0.3-1 all Mopidy extension for playing music from the Internet Archive

ii mopidy-podcast-itunes 2.0.0-3 all Mopidy extension for searching and browsing iTunes podcasts

I think that a simple `sudo apt-mark hold mopidy` should be enough, as all the other packages depend on `mopidy >= 3` and cannot be upgraded unless `mopidy` is upgraded too.

Thanks jodal.
I applied that hold and it seems the right one. Just a question, the system still asks me to update `python-spotify`. Is it safe to go on?

Yes, that can safely be upgraded. It’ll still work with Mopidy 2 and Mopidy-Spotify 3.

This is a good question for the faq (surprised this is the first occurance).
