Error adding new thing - Cannot find channel type: rfxcom:command

Context
Today I updated my OH2-offline instance to the latest snapshot since a week or 2. This reminded me of an outstanding issue that I was able to resolve:

  • Service wouldn’t start as openhab user (only as root) because karaf couldn’t start the lock manager. Resolution was to clear out the /var/log/openhab2/ folder, even though this folder and its files were owned and writeable by the openhab user

Also, after the update, all extensions were set to not-installed (I’m not sure where that status is set or managed), and as such nothing worked. Just choosing Install under Extensions resolved this. No need to reconfigure.

Current issue
Openhab cannot add channels to an RFXcom thing (in my case a CoCo motion sensor). It does succeed in adding “Signal strength”, which works, although that is only shown under Control, not in the thing configuration.

Existing RFXcom things continue to work properly.

Log shows:

What might be the issue?

I have the same problem. No channels are shown in the Thing setup in Paper UI.
