It looks like a problem with mono (it’s blowing up just as Sonarr is starting, within mono).

Have you recently upgraded mono or made other changes to the system?

5

yes… Upgraded to fedora 28 which just released.

6

Mono likely was corrupted in the process, have you tried reinstalling?

7

Yup tried reinstalling… also found out that mono-devel wasn’t installed or was maybe removed during upgrade. Installed that too… no luck yet…

It was something to do with the bug mentioned in here - https://stackoverflow.com/questions/49242075/mono-bug-magic-number-is-wrong-542
https://lists.opensuse.org/opensuse-bugs/2018-02/msg01870.html

Following the advice, changing export Term=xterm solved it… maybe temporarily and I can at least start sonarr now.
