I run openhabian on a RPI4 and used the config tool to upgrade to 3.1.0.
Unfortunately there is a bug in the homematic add-on so I am forced to downgrade until that is fixed.
Can I do it with the config tool ? If not, what would I have do on the console ?
You can use the linux shell and it is part of the documentation:
Once you know which version you want, you can upgrade/downgrade to it by using the
apt-get install openhab=[version]command, for example:sudo apt-get install openhab=3.0.0-1
The command
apt-cache showpkg openhab
shows available package versions.
I did apt-get install openhab=3.0.2-1. When asked about keeping the files I went with the maintainers version. I am now at 3.0.2 but all my add-on/tranformation configuration is gone and I cannot re-install it.

Just tried to re-install 3.1.0, now my system ist’nt even starting any more.
How did you install 'em before - via openhab-addons package ? Then that one also needs to be downgraded.
Did you try to clean the cache ? The log entry shows that it is trying to access 3.1.0 versions.
Don’t know if they came with a package. I used openhabian and they have always been there. I now did uninstall openhab and re-install it and it is back to normal - except for this annoying homematic bug.
What would happen if I downgraded only the plugins ? Or- better, just that homematic plugin ? How would I do that ?
The 3.1.0 binding would have to be removed.
And the 3.0.2 binding jar file needs to be placed in /usr/share/openhab/addons.
Make sure that the owner/group is set to openhab:openhab.
In case of incompatibilites I would expect to see a set of error messages.
It could be that the cache needs to be cleared.
Officially, downgrades are not supported so you should rebuild and restore your last 3.0.x backup./
