iobroker list adapter
iobroker list instances

c instance is alive
pi@raspberrypi:/opt/iobroker $
pi@raspberrypi:/opt/iobroker $ iobroker start admin
Cannot find any instances of "admin"!
pi@raspberrypi:/opt/iobroker $ iobroker set admin.0 --port 8081
The instance "admin.0" does not exist!
pi@raspberrypi:/opt/iobroker $

Wahrscheinlich geht es schneller alles neu zu installieren als stundenlang zu suchen . Backup ist ja täglich gemacht worden und dann üben wir das mit der Installation

Ich denke da ist auch noch mehr kaputt. Mal den Vorschlag von @paul53 umgesetzt?

sudo -H -u iobroker npm install iobroker.js-controller
Iobroker fix hat nichts gebracht nach sudo -H -u iobroker npm install iobroker.js-controller kam das hier

Das bringt so nix.

iobroker stop
iobroker fix

mal versucht?

Wenn das nicht funktioniert:

cd /opt/iobroker
sudo -H -u iobroker npm install iobroker.js-controller

Ich habe nochmal iobroker installiert

Wie genau?
