Error 'openhab-package-standard'

Hi all,

after updating to OH 3.4.0 stable, I get an error every minute:

[ERROR] [core.karaf.internal.FeatureInstaller] - Failed installing 'openhab-package-standard': No matching features for openhab-package-standard/0

I already found a possible solution here but if I remove the

 package=“standard”

it will be added after a restart again. Does anybody have a clue what is wrong with my setup?

Thanks, Christoph
