Openhabian-config - Zulu OpenJDK forces OpenHAB to restart

Setup, Configuration and Use Installation
,
1

I switched to Zulu OpenJDK (1.8.0_222) on OpenHAB 2.5M3 (openhabian) a few days ago and everything is running well so far.
But: every time I run an update via openhabian-config, java seems to be removed, openhab stopped, a fresh install of Zulu OpenJDK and restart of openhab (see logfile attached).

How can I stop this behaviour and only restart openhab when a real upgrade is performed?

Exactly what menu path are you selecting?

Hi codegrau,

I’ve had this very same behaviour with constant reinstallation of the Zulu OpenJDK, as commented here

Unfortunately no reply to my query yet, or maybe we should open another issue for this particular case.

Installed Zulu with openhabian-config [63] and trying to update with [02]

5

Do you have any zulu files in /etc/apt/sources.list.d ?
If so, delete them and retry.

I removed the zulu list but still stopping openhab.

But java was NOT un- or reinstalled this time ? Did you run apt update or did openhabian-config run that ?

You need to be more verbose. Provide the whole log, explain the starting point and carefully describe all the steps.
It’s guessing else.

Hey @mstormi
sorry for cutting the logs - even last time java was downloaded and installed.

I guess here’s the thing - so theres a stop/check/download/start of openhab every time the “update” is processed? Am I right?

openhabian-config updated.

No zulu files in /etc/apt/sources.list.d

The issue is still there for me every time I run an Upgrade System through openhabian-config, constantly re-installing the same build 1.8.0_222-b178 over and over again.

Raspberry Pi 4, initially set up with openHABian 1.5 image.

$ apt-key add openhab-key.asc 
OK

$ systemctl start openhab2.service

The only thing, which might be different to other users, is that In was bitten by the Java update error, which was briefly happening until it quickly got fixed - Openhabian config error on upgrade system

Other than not using Upgrade System through openhabian-config any longer, I’m at a loss as how to fix this issue.

I have exatly the same behaviour, als had the Update error and done the mentioned fix.
Would really aprechiate a fix.

Thanks in andvantage
