Corrupt installation after updating from 3.1 (M5) to 3.2.M4

I working on openhabian and used openhabian-config to update from 3.1 (M5) to 3.2.M4 and during the installation it fails. When checking the console there appears to the following issue.

After this operation, 20.8 MB of additional disk space will be used.

A ping and curl to the above addresses work (eg 2a00:1098:0:80:1000:75:0:3).

when trying to do a “apt-get update” it again runs into an issue

which reveals there seems to bei an issue trying to access the openhab-linuxpkg on jfrog because of missing the key.

I checked similar forum threads but with all the hints didn’t help in my case

TIA

You also tried this

wget -O -  https://davesteele.github.io/key-366150CE.pub.txt | sudo apt-key add  - 

to add the missing pub key ?

Yep, that is the one I found in the other thread and it didn’t help unfortunately.

That’s the way the supplier of the repository documented how to do it at Comitup Repository . If that does not work I would assume that the key was changed and not yet published on their page …?
You also can check if an other method on page https://davesteele.github.io/key-366150CE.pub.txt leads to an other result ( which I doubt ).

I have the same exact issue, did you find a way to resolve it and upgrade?
