But in the Whonix 15 there is already this file:
containing this line:
Is that not a ‘policykit authentication agent’?
OK. To simplify it, for now, can we therefore make it ZuluCrypt.
Again and again I import the Whonix 15 OVA (and I’ve checked its hash to make sure not corrupt), and before doing anything else (after initial wizard), I click on ZuluCrypt from the Whisker Menu and it simply gives that polkit error I’ve provided in the screenshot.
Can you reproduce this? The answer to that question will guide us where to go next.
