Hallo udo1toni,
mit Docker habe ich auch schon geliebäugelt. Allerdings fehlte mir bisher die Zeit, mich da einzuarbeiten. Und da Zeit bei mir ein Problem ist, war der Erhalt des bestehenden Systems die einfachere Variante.
Ich werde nun sicherlich auf Docker umsteigen.
Allerdings würde ich schon gerne das Problem lösen (einfach weil es da ist

).
Hier mal die letzten Ausgaben von der Installation:
