Any Idea?

I’m not sure that it’s related to the installation or upgrade method. But you were unable to reach the online path to download the addon files. Are you able to see the following page?

https://dl.bintray.com/openhab/mvn/online-repo/2.1/org/openhab/core/

Try reseting after deleting /var/lib/openhab2/cache and /var/lib/openhab2/tmp. If you’re still having problems, try installing the offline addons:

If that fails, do you use maven? Try deleting (make a backup first) ~/.m2/settings.xml

sudo apt-get install openhab2-addons

I’m able to access https://dl.bintray.com/openhab/mvn/online-repo/2.1/org/openhab/core/:
org.openhab.io.rest.docs/
org.openhab.ui.basicui/
org.openhab.ui.classicui/
org.openhab.ui.paperui/

I had already deleted /var/lib/openhab2/cache.

Deleting /var/lib/openhab2/tmp seems to do the trick.

Best regards.

Glad you have it working, I’m not exactly sure why you had a problem since both those folders are deleted on upgrade, but I suspect that your instance connected on the brief moment that the online server was experiencing issues.
