This has been reported as Debian bug #972506 gnome-software doesn't download available OS updates, but there is a workaround for it. The Software app reports a Prepared update not found: /var/lib/PackageKit/-prepared-update error when trying to update software. /var/lib/PackageKit/-prepared-update file does not normally exist, so you will not get this error if you update software from the terminal.

  • How do I "update software from the terminal"? – voddan Dec 17 '20 at 07:42

    @voddan Please run this command to update software from the terminal: sudo apt update && sudo apt upgrade This is a great way to update because it gives the user verbose output including error messages if there are any and sometimes also suggested commands to fix the error messages. – karel Dec 17 '20 at 07:44
