pseudo can't do some of the cryptsetup functions that really require root, or at least I could not convince it to. Using sudo is not so good, but I don't think there's an easy way around it for the cryptsetup stuff.

Try making it so the user doing the build is not prompted for a password when they do "sudo". I have this in my vm:

I think you can leverage pseudo tool to emulate the root user during build

    john at vbox-ubuntu-16$ cat /etc/sudoers.d/john
    john ALL=(ALL) NOPASSWD: ALL
    john at vbox-ubuntu-16$
I don't know if that's all that's needed; I have to google it every time.
