mumbledj ======== You must configure your YouTube and/or SoundCloud API keys by editing /etc/mumbledj.gcfg, as described in /usr/share/doc/mumbledj/README.md.gz. If you want to launch mumbledj with any command line arguments, the easiest way is to create /etc/systemd/system/mumbledj.service.d/local.conf containing the following: [Service] ExecStart= ExecStart=/usr/sbin/mumbledj -server=mumble.example.com -password=secret "-channel=The Lounge" -username=mumbledj #Environment=PATH=/var/lib/mumbledj/.local/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin And then run `systemctl daemon-reload` before starting the mumbledj service. See systemd.unit(5) for more information on such “drop-in” configuration files. If you prefer to install youtube-dl from pip, rather than from the Debian repositories, then you can run `sudo -u mumbledj pip install youtube-dl --user`, and then uncomment the definition of PATH above.
