    I restart the raspberry and after 3h nothing happend. Openhab does not start. The log file is not written yet (does not exist)

I have had the same problem with openhabian 1.61b. I just shutdown and manually restart.

I will try this…

Here is the status overview:

Does the output of

sudo journalctl -xe

give any hint about the root cause ?

I just saw that Java could not be found… But I didn’t deinstalled it :confused:

sudo openhab-cli start

A systemd service configuration exists…
Use ‘sudo /bin/systemctl start openhab2.service’ to start an openHAB service
Launching an instance in this terminal…
Launching the openHAB runtime…
java command not found

7

Where does the environment JAVA_HOME point to ? Does it point to a directory that includes the JAVA installation ?

8

JAVA_HOME is not set anymore… Where does it usally point?
Why is Java uninstalled from OH?

Can i just reinstall it?

9

yes, just reinstall java.

10

Which version / Java Provider do you recommend?

11

OH 2.5.X: zulu8
OH 3.0.X: zulu11

I reinstalled Java Zulu8 and it works again. Thanks for all the help!
