As per my understanding with openhabian config tool you can only update openhab to latest version, not to a specific version.
Is there any guidance / best practice if I don’t want to update to latest version?
For pure linux installations without openhabian it’s documented to use apt-get and specify the version. Is this also safe to do within openhabian or is there anything openhabian specific, why I should not use apt-get?
I had a look in the documentation and searched the forum, but did not found any hint. Not sure if I missed something or the question was not asked before?
This is safe to use on openHABian. It’s posted in a few places on the forum but ultimately you run a couple of apt commands to freeze the package to a specific version. Then run an upgrade which will only go up to tat specific version and no farther.
