The last error, about brltty-Xorg, seems to be repeated perpetually.
Proceeding with installation is not possible. Pressing Ctrl-C yields no
visible result.
This happens both with the release image from:
http://deb.debian.org/debian/dists/buster/main/installer-amd64/20190702/images/netboot/xen/
and the latest nightly built from:
https://d-i.debian.org/daily-images/amd64/20190715-00:24/netboot/xen/
Providing "-- console=hvc0", "-- console=tty0", "-- console=" and "" as
values for the 'extra' config variable makes no difference. No additional
config options in xl.cfg, apart from pointing out kernel and initial
ramdisk.
To the best of my understanding, this issue is not mentioned in neither the
Release Notes nor the Installation Guide for Buster. The Xen page on
Debian's wiki is also a bit thin on Buster specific details.
For what it's worth Dom0 is running Stretch with Xen 4.8, and has several
fully functional DomU instances also running Stretch.
One might guess #768657 is related in some way, but unfortunately I do not
currently fully understand it. I'm reluctant to post directly to it since it
seems too old (November 2014) to be causing failure only for Buster, but
please feel free to merge this report with it if confident the issue is
caused by the same root cause.
