Openhabian Upgrade from OH2 to OH3 failed

Dear all,

Upgrade of OpenHAB2 (openhabian) to OpenHAB3 by openhabian-config does not work on my Raspberry Pi 4 Model B 4GB.
The issue seems to be a missing key. But how do I solve this?

I think the steps described in Installing Comitup · davesteele/comitup Wiki · GitHub :

dpkg -i --force-all davesteele-comitup-apt-source_latest.deb
rm davesteele-comitup-apt-source_latest.deb

should do it.

With regard to

I would assume that Raspbian needs to be spelled in lower letters.

Thanks Wolfgang!
I don’t need comitup and I am not aware to have installed it.
Or what does „Get“ mean instead of „Hit“?
Is there a way to delete/exclude it from the update list?

In directory /etc/apt/sources.list.d you find a list of files.
One is most probably called comitup.list.
If you do not need that repository you can delete the file or rename it ( add an other file extension ).
Doing so should ignore it at next run of apt update.

That solves the problem of apt-get update. :+1:
I will try the OH3 upgrade once again tomorrow.
For homegear I found this solution:

I would assume OP uses an ancient version of openHABian, he failed to tell.
If you run homegear setup again it should deploy the correct repo.
