Windows 10: 1809 update fails with 0x800F081F error

I downloaded MediaCreationTool1809.exe and used it to create an installation thumb drive for Win10 x64 1809. I used the thumb drive to update my laptop to 1809 (running setup.exe off the root of the thumb drive), and that completed without problem. After a couple of days without problems on the laptop, I used the thumb drive to update my desktop via the same process, but after performing the initial part of the update, and then rebooting to continue it, setup eventually came back with a window titled "Windows 10 Setup" and containing the text:

We couldn't install Windows 10
We've set your PC back to the way it was just before you started installing Windows 10
0x800F081F - 0x20003
The installation failed in the SAFE_OS phase with an error during INSTALL_UPDATES operation

A bit of googling showed a couple of possible causes for the problem, but they don't seem applicable - I'm not using 3rd party antivirus, and C: has sufficient free space (~35Gb free). Any suggestions on a fix?

Solution for error 0x800f081f for Windows 8.1 or Windows 8

If you receive Windows Update error 0x800f081f, it means that Windows Update cannot determine the cryptographic service provider, or a file that Windows Update requires (named catalog store) is corrupted.
To resolve this problem, follow these steps:
Step 1: Use System File Checker to repair damaged Windows files
Use the System File Checker tool to repair damaged Windows files, and then run Windows Update again. To do this, follow these steps:

• Open an elevated command prompt.
• Run the following command:
  sfc /scannow
• Try to install update again.

For more information about the System File Checker tool, view Use the System File Checker tool to repair missing or corrupted system files.
Step 2: Run the DISM tool
If the problem continues, use the Deployment Image Servicing and Management (DISM) tool to fix Windows corruption errors. To do this, follow these steps:

• Open an elevated command prompt.
• Run the following command: DISM.exe /Online /Cleanup-image /Restorehealth.

Important When you use the /online option, DISM uses Windows Update to provide the files that are required to fix corruptions. However, if Windows Update service is broken, don’t use the /online option. Instead, use a running Windows installation as the repair source, or use a Windows side-by-side folder from a network share or from a removable media, such as the Windows DVD, as the source of the files. To do this, run the following command instead:
DISM.exe /Online /Cleanup-Image /RestoreHealth /Source:C:\RepairSource\Windows /LimitAccess
Note Replace the C:\RepairSource\Windows placeholder with the location of your repair source. For more information about using the DISM tool to repair Windows, reference Repair a Windows Image.
To learn more about this tool, go to Fix Windows corruption errors by using the DISM or System Update Readiness tool.

   2. Point the "Alternate source file path" to the ISO sources\sxs folder from the ISO.
   3. Run the gpupdate /force command.
