Hi again, thank you very much for all the suggestions that you shared
with us.

Finally we find a solution.

What was the problem? If we created an ISO image of Devuan Beowulf with
Mate, and we wanted to run d-i from live mode, it did not run in GUI
mode, it opened in text mode. Using su-to-root and pkexec.

On the other hand, if we tried the same from a Devuan Beowulf ISO with
XFCE or LXQt, it works without problems. Using su-to-root, d-i runs in
GUI mode. ¯\_(ツ)_/¯

After trying in many ways, we managed to get the launcher to work in the
Mate version using this command:

`pkexec mate-terminal -e /usr/sbin/debian-installer-launcher`

We were left wondering why in XFCE it works with su-to-root and with
Mate we have to resort to launching it using pkexec in that way?

Thanks again :)


PS: In this URL: http://distro.misiones.gob.ar/ultima/beta/
are the beta versions where we were doing the tests,
there is a version with XFCE, another with Mate and one that includes
both. The version with Mate has already corrected the command in the d-i
launcher on the desktop, but you can try running from the terminal with:
`su-to-root -X -c /usr/sbin/debian-installer-launcher` or
`pkexec /usr/sbin/debian-installer-launcher` to see the behavior.
