I tested an upgrade from Impish to Jammy today in a virtual machine and from what I could tell (I didn't watch the whole process) the upgrade did not stop when dbus was installed although the message posted in the screenshots was display. Looking at my /var/log/dist-upgrade/main.log we can see that the total upgrade took only 16 minutes so it's unlikely that 10 of that was spent waiting.
