I don't remember what I did in the past, but I was able to reproduce the dialog with the following steps: 1. Upgrade fully and reboot the system. 2. Downgraded a package: sudo apt install unattended-upgrades=1.1ubuntu1 3. Disabled u-u: sudo dpkg-reconfigure unattended-upgrades 4. Opened Gnome Software (Ubuntu Software) 5. Clicked on Updates tab, then on the refresh/reload icon in the upper left corner. Gnome Software printed "Looking for updates", then misleadingly that "Software is up to date" despite u-u is still not upgraded. 6. The prepared-update file is now present: $ ls -alh /var/lib/PackageKit/prepared-update -rw-r--r-- 1 root root 93 srp 18 12:24 /var/lib/PackageKit/prepared-update 7. Clicking on Shutdown now offers installing updates which is executed, too. Upon next login a report is shown about installed updates.
