[SOLVED] OH2 does not start after upgrade to openhab2_2.1.0~20170515205429-1_all.deb

Hi,

I just did an update/upgrade of openhab2 via apt-get to version openhab2_2.1.0~20170515205429-1_all.deb.
Since this my openhab2 does not startup anymore.

The log file is empty, no KARAF shell is available and sudo systemctl status openhab2.service says:

pi@raspberrypi:~ $ sudo systemctl status openhab2.service

and here it stays forvever…

Any Ideas?
Thanks

btw.
I already did a reboot and a apt-get install --reinstall…

without changing anything… OH2 works again now…
