I’m using OpenHAB on a QNAP NAS (TS-673), via Container Station (their Docker envelope). Currently running OpenHAB 3.4.4 and I thought it’s time to upgrade. Wanted to upgrade first to 4.3.9 and make it work again, then upgrade to the latest 5.x version, assuming this is the safest way to adjust for “breaking changes”, having read the release notes.
Unfortunately, after I created and started the new OpenHAB 4.3.9, I get the error “KARAF_ETC is not valid: /openhab/userdata/etc“ which then aborts the start of the container.
This is the full log of the container start in the QNAP Container Station:

Launching the openHAB runtime...
KARAF_ETC is not valid: /openhab/userdata/etc
Searching the forum / internet for this, I saw some postings from 2020 with this error. There were discussions around the openhab folders, access rights and some said the userdata/conf/addons folders need to be empty on first start to avoid the issue.
I was running 3.4.4 via the 9001 user. Yes, shame on me, bad practice, but it worked. So given this error I decided to fully follow the OpenHAB guidelines, created an openhab:openhab user/group, and added their IDs to the docker parameters. Didn’t help. I manually changed ownership of the openhab folder to openhab:openhab, I made sure all files & folders inside have this ownership, didn’t change anything. I also then tried to start the 4.3.9 container with an empty folder, also didn’t change anything.
Luckily I took a backup of the old folder and could make it run with the 3.4.4 container again, so currently OpenHAB is running fine again with the (very) old container.
Any help or hint towards a solution would be much appreciated. What did I miss when I tried the upgrade?
