@Brian Murray:
Yes, today i ran into this issue on 2 servers. The install stalled after "A reboot is required to replace the running dbus-daemon.", and then the installer resumed after 10 minutes.

The first server i upgraded I've been caught by the misleading "Please
reboot the system when convenient." and just rebooted after a few
minutes because the installer was doing nothing.

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

Status in dbus package in Ubuntu:
  Incomplete

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.
