I'm pleased for you that it now appears to be working so this comment comes after the fact. You are asking three separate questions here, in some sense: You have a Chromebook - so ChromeOS underlying everything, potentially A Xen subsystem running Devuan - note, not Debian A Debian 12 as the guest OS? The number of folk on this list with a Chromebook is small, potentially. The number with Xen experience is a subset of that. The number with Devuan experience is a subset of that. You were very fortunate indeed that someone here was able to resolve anything. For the future: * For Devuan, please ask their support channels on IRC - https://www.devuan.org/os/community or their mailing lists on DNG - https://mailinglists.dyne.org/cgi-bin/mailman/listinfo/dng * Ask _their_ experts for expertise with Xen under Devuan After you have exhausted Devuan expertise, please write up what advice you have already received and then come to Debian. As often reiterated here: this mailing list only has significant expertise in Debian, and not necessarily every Debian-derived distribution.
