Oh, sorry, my mistake… I mean “I can’t create Disposable VMs now”, not template VMs… I mixed it with my other question (How can I create a template HVM of any OS?) asking how to create a template of any OS.
But my main problem is I have deleted the default Qubes disposable VMs, and since I mainly use the GUI, I don’t know how to recreate it using CLI yet.
Also, I have tried to create a disposable VM using Qube manager, but when I click “create new Qubes VM”, the VM options are:
Qube based on a template (App VM)
Standalone qube copied from a template
Empty standalone qube (install your own OS)
But I’m going to try @unman 's and, @51lieal tips. Thanks guys, and sorry for being annoying
