ich bin gerade dabei meinen iobroker vom RaspberryPi 3b in eine Debian 9 VM zu migrieren.
iobroker konnte ich dort auch erfolgreich installieren.
Nun scheitert mein Vorhaben zunächst an der Wiederherstellung des iobroker Backups vom Pi.

Das erstelle Backup habe ich in einen neuen Ordner "backups" unter /opt/iobroker/ hochgeladen.
Hier der Fehler nach Ausführen des Restore:

andre@deb-iobroker:/opt/iobroker$ sudo iobroker restore 0
/opt/iobroker/node_modules/iobroker.js-controller/lib/setup/setupBackup.js:568
        if (parseInt(name.trim(), 10).toString() === name.trim().toString()) {
                          ^

Den Fehler habe ich so interpretiert, dass offenbar irgendetwas mit dem js-controller nicht in Ordnung zu sein scheint.
Also probiert js-controller manuell zu installieren:

andre@deb-iobroker:/opt/iobroker$ cd /opt/iobroker
andre@deb-iobroker:/opt/iobroker$ sudo npm install iobroker.js-controller

Nun gibt es scheinbar ein Berechtigungsproblem.
Ich habe dann versucht über root und "usermod -aG sudo andre" probiert den user zur Gruppe sudo hinzuzufügen.
Das Berechtigungsproblem bleibt aber bestehen.

Weiß jemand weiter?

Grüße
Andre
