Error: type error qubesbase.clone_vm () takes 3 positional arguments but 4 were given

I just wanted to create a new TemplateVM, but suddenly I got this error message “error: type error qubesbase.clone_vm () takes 3 positional arguments but 4 were given”.

How can I fix this error?
All updates have been installed, so this is certainly not the problem.

The fix for this is currently in the testing repository:

If you want to install the package before it is sent to the stable repository, you can use the following command in a dom0 terminal:

sudo qubes-dom0-update --enablerepo=qubes-dom0-current-testing qubes-core-admin-client-4.2.17

Or right click template and select “clone” and then rename cloned template?

That’s funny! If the quality of the “stable” repository (or more exactly “the lack of…”) led to this error… is it reasonable to install from the testing repository? :laughing:
