Test 'Universelles Update-Skipt / Systempflege'

Thomas Braun

Ich hab mal (mit ein wenig Support seitens der KI 'Le Chat Mistral') ein generelles Update-Skript gebastelt.
Den nachfolgenden Code auf dem System abspeichern und ausführbar machen.

Das Skript deckt

Paketupdates einer Debian-Installation ab (aber keine Dist-Upgrades/Release-Wechsel!) inkl. nodejs-Updates innerhalb einer Major-Version (aber keine Wechsel der Hauptversion oder Reparaturen daran)
Updates des js-controllers (Das muss am intensivsten getestet werden!)
ioBroker-Adapter-Updates

ab .

Bitte NICHT auf Produktiv-Systemen testen, nur auf ausdrücklichen Test-Systemen, bei denen es 'egal' ist, wenn die über den Jordan gehen.
