Volume group “system” not found after initial installation


I have the same problem as mentioned here: Volume group "system" not found or here: Gave up waiting for root file system device. Dropping to a shell!

Here are the steps to reproduce on an Intel NUC 5 with a NVMe card:

  • Boot from yunohost-bullseye-11.0.9-amd64-stable.iso
  • Keep everything as default, except LVM encryption
  • Wait until installation finishes

After the reboot, the system does not start, instead the following message is displayed:

Volume group “system” not found
Cannot process volume group system

I will now install Debian and yunohost on top of it, since it worked for me in the past. But it looks like a bug. Maybe the Debian version that yunohost-bullseye-11.0.9-amd64-stable.iso is based on is too old?

I dunno, our .iso is built with Simple-CDD-Build thingy from Debian : Simple-CDD/Howto - Debian Wiki

which supposedly is just tweaking the official install iso from Debian / should be equialvent

Yet I’ve seen many people reporting that they get funky behavior sometimes

So i dunno what happens, and I don’t know how to get like a “real” Debian ISO that does work “as much as” Debian’s iso …

When installing Debian, I noticed that it mentioned UEFI at various locations. It was not the case with the Yunohost ISO. I assume that the issue is related to this. Maybe the latter installs the OS using the legacy BIOS mode and this causes the trouble.
