As Adam indicated, hwdb no longer exists and hasn't for some time. The bug can not and will not ever be resolved as none of the component parts (especially the projects the duplicates were filed against) exist any longer. They have either been abandoned, or transitioned to newer projects.
For completeness, anyone looking for an official list of hardware supported by Ubuntu, they should look to https://certification.ubuntu.com
