Comment 3 for bug 2049798

While this might still be a bug in subiquity, the fix I did to the snapcraft.yml in edubuntu-desktop-installer[1] for sure fixed the issue, meaning, from an edubuntu-desktop-installer perspective, this is fixed.

That said, I'm not sure if subiquity needs to fix this themselves to include this in the subiquity snap, but it definitely points to lvm2 and mdadm being necessary dependencies of subiquity.
