Here is the re-post ( Without the link i’m not allowed to post ) of mine from the old forums for those having trouble installing serviio media server .
I could not find anything on installing it under Manjaro but found the script on the Arch user repository . If anyone else has been looking to install it you can find it in the AUR. You can use it to build your own package . I used Pamac to create my package . After install use these commands to get it going .
systemctl start serviio.service ( Starts the service and it will start at boot . )
systemctl stop serviio.service ( Stops the service )
systemctl status serviio.service ( Will show you the server status )
After its installed you will have an icon under multimedia that will let you configure the server .
Hope it helps someone else from searching for hours .
