Title:
  block probing crashed with ValueError - Invalid dep_id (disk-nbd0) not
  in storage config - PXE Install

Status in subiquity:
  New

Bug description:
  Using a tool called iVentoy to mount the ISO under device nbd0 using
  PXE Boot we get the following error as soon as the installer window
  pop-up.

  NB:
  - Using rufus to install with an usb stick instead works without any issue.
  - Legacy installer (Ubiquity) also works in PXE mounting nbd0 without issue.
