Hello @mstormi ,
Thank you for your answer.
I tried, but had the same result. But I found out that, even if I was quite sure, that I have buster running, and not bullseye. Sorry for the wrong information. Could this be the source of the issues? I have tried both
deb [trusted=yes] http://mirrors.ocf.berkeley.edu/raspbian/raspbian bullseye main
and also
deb [trusted=yes] http://mirrors.ocf.berkeley.edu/raspbian/raspbian buster main
but the results stayed the same.
As a next step I have re-created my Openhab with the latest Openhabian image and restored my backup.
In general it worked perfectly well, Java 17 and everything is there, but I got stuck with another issue with the Enocean Add-On, which is not able to connect to the USB300 Enocean stick, which is also mentioned in EnOcean USB300 initialization fails with OH 4.0.0.M3 and OH 4.0.0.#3512
So, finally, I switched back to Openhab 3.4.4 (runs like a charm) and need to find a solution later, but I doubt I find the time before the weekend.
