Fails setting ZRAM dependency after migration to OpenHAB3 (not sure if I was using ZRAM in the base case)

[BigGeorgeTx]

Issue information:

I tried to migrate to OpenHAB3 using openhabian. It seems like the install was working, but then it failed.
I can force OpenHAB3 to run with openhab-cli start --debug. It runs and I can access the new UI. But that only lasts for a while and then it stops.

As instructed, I increased the openhabian debug to maximum. It seems to be having a problem adding zram dependency. I don't recall if I ever had ZRAM set up on this PI or not. This was my first venture into SBC and OpenHAB. I remember being a little concerned about SD card wearout and reading about ZRAM, but honestly can't remember if I ever tried to set it up or not. When I enter systemctl status zram-config.service, it says there is no such service. I tried uninstalling and reinstalling zram using the openhabian-config menu, but encountered errors either way.

You're choking on a number of issues unrelated to openHABian here. You must not start openHAB manually but use the existing service (systemctl status/start/stop openhab). Then all your trouble is because ZRAM is not installed in the first place. Use menu 38 with debugmode=maximum so you can see if it proceeds.

Please next time do not open a Github issue unless you're convinced there is a problem in openhabian. Github is not a support ticket system, make a post on the forum instead if you need help debugging.

I apologize for putting this in the wrong form. I misunderstood the discussion on and thought that because I had run into a problem using openhabian, I should address it here rather than in the OpenHAB community. I have noted the error I got trying to install ZRAM there and will look there for help in finding a solution.

Should I delete this issue that I raised, or it is better to just leave it alone at this point?

[mstormi]

just leave it, it's closed
