Emby Server does not restart from the web interface

Emby on Linux does not have the built-in capability to restart itself. So to restart Emby uses a helper script. The helper script named restart.sh can be found on most distributions at /usr/lib/emby-server. The script can only restart Emby if it was started by a service manager program such as systemctl or service. If for some reason the helper script does not successfully restart Emby for you, please check the following:

• Ensure helper script is executable.
• Ensure Emby was started via a service manager.
• Ensure permissions of /etc/sudoers.d/emby are 0640
• Ensure whatever user is running emby-server is part of the emby group (usermod -a -G emby $USER_NAME)
• Ensure /etc/sudoers permissions is 0640

Example of troubleshooting restart on a distribution using systemd

1. sudo systemctl status emby-server - Get PID.
2. Hit restart on web interface
3. sudo systemctl status emby-server - Get PID.

If PIDs differ restart was successful. Otherwise, check the following:

1. ls -la /usr/lib/emby-server/restart.sh - ensure it is executable.
2. ps -aux | grep emby - Take note of PID
3. sudo -u emby /usr/lib/emby-server/restart.sh - if you are running emby-server as another user other than emby, please adjust command appropriately.
4. ps -aux | grep emby - Take note of PID

If PIDs differ restart worked.
