iobroker stop
iobroker fix
iobroker start

Und dann gewöhn dir das ständige 'sudo' ab. Das wird gar nicht soooo häufig im Zusammenhang mit ioBroker verwendet.

iobroker start

...Was soll ich sagen...

Ihr seid die geilsten!

Es läuft!
Vielen Dank.

Du nutzt deutlich zu häufig 'sudo'. Lass das, wenn es nicht notwendig ist.

Oder für was wurde dieser Teil der Doku geschrieben?

Die Versionen sind jetzt gleich... v.12.6.3

Allerdings bekomme ich keinen Zugriff auf IOBroker.

Muss ich bei NodeJS ein downgrade durchführen, oder was könnte es sein?

Ist nicht korrekt, du brauchst kein sudo an der Stelle.

Und dann ist dein node nicht richtig installiert. Die Versionen von node und nodejs müssen übereinstimmen.
