Hi,
I had the same issue and I used the "Create Windows 10 installation media" to perform an "upgrade":
KB4493509 fails to install

Hello everyone,
this is the first update since upgrade to 1809 that fails to install. I tried everything. Manual downloading, but even manual installing at the end just shows message, that the update couldn't be installed, without any errors. At Windows Update, it's shown an error 0x800f0982. I've done sfc /scannow, no corrupted files. I've done Restorehealth etc, and the error is still there. This is the first time that has happened to me. So should I wait for next update? Or what to do?

This process takes 2 hours but it effective.

Search for "hide windows updates" widget, download it (very small and quick), run it and hide the update that's not installing. Restart your PC. Run that widget again and unhide the update. After it's "fixed", try Windows update. Then check the installed updates: magically, it will be there as "installed". Don't ask me why but it worked for me ;-)
