Error 2.5.0 m3 openhabian


Failed installing ‘openhab-misc-restdocs’

restdocs is now under ui, not misc. That is mentioned in the warnings when you upgraded.

Welcome back to the OpenHAB community Giuseppe!!!
As Bruce said, the Rest documentation has moved in 2.5
Hope it works for you, depends on what other stuff you’re using, if you have troubles see here

and a workaround here
