Mopidy installation and issues

It took me a while (like 4 attempts) to get mopidy working.

If it is installed from apt and works - great. (not in armbian and orangepi case).

If not - there are a lot of broken dependecies.

Just follow the errors trail and it would be easy to find what’s wrong.

TLDR:

Use python 2.7 and older version of mopidy to avoid all problems (if you don’t need all the greatest and latest features):

pip2 install --upgrade --force-reinstall mopidy==2.1.0

Add Systemctl file

[Unit]
Description=Mopidy music server
After=sound.target

[Service]
User=mopidy
ExecPre=/usr/local/bin/mopidy --config /etc/mopidy/mopidy.conf local scan
ExecStart=/usr/local/bin/mopidy --config /etc/mopidy/mopidy.conf

[Install]

sudo systemctl daemon-reload;

sudo systemctl restart mopidy.service ; journalctl -u mopidy.service -f;

sudo chown -R mopidy /var/lib/mopidy

sudo chown -R mopidy /etc/mopidy

Issues after install

Going the hard way - attempt to install latest version:

apt install mopidy

Nothing here - you’ll need to compile this package manually, since only older version exists in repo…
