Continuing the discussion from Qubes 4.1.0-beta1 Available:
Solved, I created a new dvm-d10 DVM template and got its Disposable:* entries in Qubes Menu. It launched the randomly named dispvm .
I don’t know why the default debian-10-dvm DVM template don’t show its Disposable:* entries in Qubes Menu. The debian-10-dvm
appmenus-dispvm feature is 1.
The error is:
Rendering SLS 'base:update.qubes-vm' failed: Jinja variable 'dict object' has no attribute 'os_family'
The issue already exist : #6771.
