[Bug 1982903] Re: Installation fails on machine with Intel VROC

[Dan Bungert]

We believe a fix for this can be found in Subiquity 22.10.1.  On install you
will be offered to update to the new version of the installer if network is
available, or you can perform a manual update by performing a
sudo snap refresh subiquity
from a debug terminal.


** Changed in: subiquity (Ubuntu)
       Status: Fix Committed => Fix Released

Title:
  Installation fails on machine with Intel VROC

Status in subiquity package in Ubuntu:
  Fix Released

Bug description:
  I'm trying to install Ubuntu 22.04 on a server which has two M.2 disks
  in RAID 1 using Intel VROC.  If I accept the prompt to update
  installer to 22.07.1, then it fails while probing for destination
  blocks devices.  If I proceed without updating, it works fine.

  The server is a Supermicro 740GP-TNRT.

  I'm attaching the full output from `/var/log/installer` and I believe
  the relevant portion is this:

  ```
