During the installation there are some error/warn message appearing in the log, which seem to be completely unrelated (UI, HabPanel, MQTT)

OpenHab is starting, but gets stuck. Nearly all things are reported as “NOT YET READY”

Everything is fine again, except of one exception, which seems not to have an negative impact, but the JRuby Add-on is reported as not installed.

I can repeat these 3 steps with the same results.
Now I’m a bit lost on how to dig into the problem and any hint is highly appreciated.
I’m not even sure if the problem is related to the JRuby Add-On but to a perhaps bigger issue with my installation.

2

Can you try to uninstall JRuby addon and see if that makes a difference?
Did you install all your addons using the MainUI?

Thank you for your reply @jimtng
I have installed all add-ons from th UI.

Meanwhile I digged a bit deeper into this and found, that I do not have a specific problem with the JRuby Add-On, but a more general one with installing new Add-Ons. They show pretty much the same behaviour.
So it looks as if I have a general issue with my system.
I will open a new posting, trying to describe the general problem.
