[Bug 1968845] Re: Upgrade to 22.04 from 20.04 ends with dbus installation asking for a reboot

[anne ranch]

This bug STOPS 22.04.1 version - all generic - include 5.15.0.52 \
booting process from completing. It gets stuck "loading d-bus message"
(package ?? ) - in infinite loop....


How do I downgrade to WORKING Ubuntu version when I cannot get the boot process to complete ????? 

I have two Ubuntu partitions (22.04.1) and they both fail SAME way. 
I have older Ubuntu versions /partitions and they boot as expected ....

I do need to recover the faulty 22.04.1  and keep the partitions they
are in INTACT.

PS I think this is a wrong place to ask for help... but I would
appreciate held without being told where to ask....

Title:
  Upgrade to 22.04 from 20.04 ends with dbus installation asking for a
  reboot

Status in dbus package in Ubuntu:
  Invalid

Bug description:
  Upgrading on a virtual machine from 20.04 to 22.04. I have had this
  happen twice now, I got one upgrade done without this bug.

  Basically the package installation stops at dbus package asking for a
  reboot as it was unable to upgrade as dbus-daemon was running. And
  rebooting at this stage obviously will cause a non-functioning system.

  Added a screenshot of the upgrade window.
