Hallo,
ich habe heute die neue 6.5er ISO heruntergeladen, per sha256sum überprüft und auf einen USB Stick kopiert.
Der Stick bootet auf einem UEFI Board einwandfrei.
Die Installation klappt allerdings überhaupt nicht, da sie nicht startet.

Der Start von Calamares bricht mit folgender Fehlermeldung ab:
