let’s try to check the process ID

ps -ef | grep 456

ps -ef | grep 456
www-data     456       1  0 Jul17 ?        00:00:02 /usr/bin/mono /usr/lib/mono/4.5/xsp4.exe --port 8084 --address 0.0.0.0 --appconfigdir /etc/xsp4 --nonstop

Did you installed something like mono-xsp4 web server? At least it is configuration to ran on port 8084

11

I think at least with older Mono versions this xsp4 server is started automatically.

@caio1007
Which hardware/SBC do you use? If it’s not an RPi 1 or Zero, all but Sonarr can run without Mono nowadays, even Sonarr without this xsp4. Reinstalling/Updating Radarr should allow you to uninstall Mono.

12

I use sonarr and radarr.
I use raspberry pi 4 4 gb, which command do I use to uninstall mono? if i uninstall my sonarr will it stop working?

13

could you share following?

  • DietPi version | cat /boot/dietpi/.version
  • Distro version | echo $G_DISTRO_NAME $G_RASPBIAN
  • Kernel version | uname -a

@MichaIng
Sonarr still requires Mono, isn’t it?

Found it, an enhancement we did with DietPi v8.0, skipping mono-complete and installing only mono-devel which leaves out XSP4:

apt install mono-devel
apt purge --autoremove mono-complete
