If that doesn’t work, check your network and firewall settings. Something is preventing OH from reaching the service where the add-ons are downloaded from on the Internet.
As a last step, you can download the add-ons.kar file that corresponds to your version of OH (release, milestone, snapshot) from Download openHAB | openHAB. Place that file into the addons folder (see the installation instructions page for your OS for where that folder is) and OH will get the add-ons from the kar file instead of the Internet. But remember when you upgrade OH you’ll have to download the kar file again.
I am on 3.3
What i did is reboot several times but the messages come again.
Clean - cache - The system is not responsive after the reboot, need to restore from backup bit I fear that this brings back the zombies sleeping in my config.
I downloada the add-ons.kar file, placed it in addons folder and got the following message:
2022-10-06 17:31:53.905 [INFO ] [core.karaf.internal.FeatureInstaller] - Some .kar files are not installed yet. Delaying add-on installation by 15s.
Seems that it solved, no really idea how.
I stopped the service, cleaned the cache, started again, and again i didn’t come up (basic ui).
After a reboot i saw 14 apt updates, did an apt-get upgrade and update.
started the console and did a feature:refresh and for the first time not jetty errors appeared.
Now it is up and running and the erros have disappeared.
