That is strange. I was going to suggest you manually install Mono from their website but they are saying the latest stable release is :

The latest Stable Mono release is: 6.12.0 Stable (6.12.0.199)

The dependency check says you need to be greater than or equal to 6.12.0.200 so that is not going to work either. If you want you could try it and see what happens…

How To Install Mono on Ubuntu 22.04 LTS

I run Sonarr in docker and I just checked to see what version of mono the container is running (with docker the containers look after dependencies such as mono)…

Tried that procedure but no joy.

It failed at sudo apt install mono-devel, with pretty much the same problem:

I’ll ask around some of the Mono discussions and report back here if I find a solution. It is a bit worrisome that the “official” Mono install process still uses the deprecated apt-key.
