disp vm template not working in fedora 31

[galth...@gmail.com]

Hello, I hope someone can help with this.

I have a modified fedora 31 template which I want to use as a disposable VM.

I have done this:

Created a app vm called my-dvm based on my-f31-template using the qubes manager

In the dom0 terminal:

qvm-prefs my-dvm template_for_dispvms True

qvm-features my-dvm appmenus-dispvm 1

There are no error messages but I dont get the 'Disposable' entries in the start button menu. So I did this:

qvm-appmenus --update --force my-dvm

my-dvm: Creating appmenus
Traceback (most recent call last):
  File "/usr/bin/qvm-appmenus", line 9, in <module>
    load_entry_point('qubesdesktop==4.0.20', 'console_scripts', 'qvm-appmenus')()

    appmenus.appmenus_update(vm, force=args.force)

    dispvm):

    raise DispvmNotSupportedError()
qubesappmenus.DispvmNotSupportedError: Creating Disposable VM menu entries not supported by this template

How can I fix this?

I am looking  for what I think is a similar answer   If I create a clone of a template, Choose Qubes Settings. I change the color of Qube to red.   The second tab is Advanced.  on down in the left column there is a reference to what the Default template setting is.   hmm.   where to go from here.

Same problem on my side.

I followed the documentation and successfully created a new DisposableVM Template after (new)installation of R4.0.3.

Also I managed to setup a different DispVM, based on a modified fedora-31-template, with no trouble.

I usually, in my previous installation, just created an AppVM 'xyz' and set the "Disposable VM Template" property via Qubes Settings. After logging out and in again I found the corresponding "Disposable: 'xyz'" menu entry. Did not need to manually set the appmenus-dispvm feature.

But currently I cant get right.

Even if I follow the same steps that I used for the default DisposableVM, which worked before, it wont anymore!? The error message is exactly llike the one gath... posted.

Sidenote: I can run a dispVM off of that 'xyz'-template via dom0: qvm-run --dispvm=xyz --service qubes.StartApp+xterm. Only the menu entries aren't behaiving as expected.
