Screenshot of Sonarr complaining about Mono version
Sonarr reports in the latest version:
"Currently installed Mono version 220.127.116.11 is no longer supported. Please upgrade Mono to version 5.20."
Please change the dependency in net-p2p/sonarr-devel from mono-5.10 to mono-5.20. Thanks.
Mono 5.20 has never worked on FreeBSD. There is work to get Mono 6.x but it has stalled out. The history is here: https://reviews.freebsd.org/D23300
I can't provide more details or guidance, but this is beyond the scope of this port/package.
