I have made this script and it is pretty much fully functional and works with Feral and whatbox (with slightly different setups) but there are potentially a few bugs.
it installs mono/sonarr/jackett/emby
1: whatbox does not like form auth method
2: feral does not like basic auth with nginx + proxypass
try it out and see what you think and if you find issues let me know.
If you have used Feralhosting all the other scripts are me to so this is not some random script.
wget -qO ~/install.monoapps https://git.io/vzyZ4 && bash ~/install.monoapps
