JRiver 27 seg faults in Gear Isolation

[Primare11]

Sorry, no hit.
In the ~/.jriver/Media Center 27 folder is the following folders 
 

PHP Code:

root@ubuntu20lts:~/.jriver/Media Center 27# ls -l
total 24
drwxr-xr-x 2 root root 4096 Jun 27 12:25 Data
drwxr-xr-x 2 root root 4096 Jun 27 12:30 Library
drwxr-xr-x 2 root root 4096 Jun 27 12:30 Settings
drwxr-xr-x 4 root root 4096 Jun 27 12:25 Skins
drwxr-xr-x 2 root root 4096 Jul  1 15:33 Temp
drwxr-xr-x 4 root root 4096 Jun 27 12:25 Visualizations 


I can't find any Log.txt or similar file in any of those folders, all files except Temp was created when I install Jriver, and the Temp folder is empty.

So, I will try to install Snakeoil on a real PC and see if it's works.

I have now install Ubuntu server 20.04 and Snakeoil 1.2.1 + Jriver 27 on an old NUC5 if have, but it's still the same problem; mediacenter27 segfault 10 error 4. 
I have also tried to install both Jriver 25 (that I has running on Snakeoil 1.1) and Jriver 28 but none of them is showing up in the Snakeoil media servers list, so I cant start them.
Is there any way to manually enable Jriver 25 so it starts automatically or manually (just to try to narrow down the problem)?   
or is it possible to add the possibility to enable Jriver 25 and Jriver 28 in the next Snakeoil release?
