Qubes Agents for Ubuntu Bionic

Hi, Is there any way to get qubes agents for Ubuntu 18.04? I need them for HVM of Caine. I try to build them with Bionic template but there is some bug and that builds fails. When I search for that bug I found open issue for it on github so I assume that is impossible to build whole template… But maybe I can just build individual tools? What tools I will need for HVM?

take a look at unman ubuntu repository, there’s bionic in 4.0
you may want to use focal in 4.1.

It’s almost impossible to put packages in to a standalone without
breaking it, particularly for Ubuntu.
I don’t think your plan will work.

So there is no way to pass USB to linux HVM and share files with it?
