OH not starting after clean cache

Setup, Configuration and Use Runtime

Platform information:

  • Hardware: Rasp pi 4
  • OS: openhabian 3.0.1

Hi all
I wanted to clean the cache so I used the following thread:

I run the commands:

sudo /bin/systemctl stop openhab.service
sudo openhab-cli clean-cache
sudo /bin/systemctl start openhab.service

After that - the OH not start :frowning:
I rebooted and the OH not starting.
The output of

 sudo /bin/systemctl status openhab.service

is :

Warning: The unit file, source configuration file or drop-ins of openhab.service

lines 1-13/13 (END)

The only thing that starts the OH is the command:

 sudo openhab-cli start

Can someone tell me what I messed ?
Thank you!

If you nonetheless plan to stay on an older openHAB release, please download the add-ons KAR

In addition to what sihui brings up, there is only one time where clearing the cache is advisable or necessary: when there is a problem installing/uninstalling an add-on. All clearing the cache does is force openHAB to redownload and install all the add-ons.

But what add on do I need to get the service running again after restart?

That isn’t controlled by an add-on. But by clearing the cache you now have forced OH to reinstall all the addons.

And as the link sihui explains, the add-ons are not longer on Bintray. You need to upgrade to 3.0.2 or later so that OH will look for the add-ons in the right location.

Thanks for the response.
I will upgrade to 3.0.2.
But I didn’t manage to understand if it will fix the restart issue.

7

the command

sudo journalctl -u openhab

might do.

Edit : Issue solved by the command:

sudo openhab-cli  reset-ownership

Thank you for the help!
