Managing Windows 10 1909 machines on Workspace ONE UEM Cloud with the CIS L1 1909 Baseline applied. When manually checking for updates on the machines, it attempts to update to Windows 20H2 but fails at the end of "Getting things ready". For some reason, when the baseline is applied, it also attempts to update Windows Subsystem for Linux Update 4.19.128 and fails (removing the baseline results in a successful 20H2 update and the WSL update isn't event attempted). The two errors are:
There were problems installing some updates, but we'll try again later.
Feature update to Windows 10, version 20H2 - Error 0xc1900223
Windows Subsystem for Linux Update - 4.19.128 - Error 0x80070643
Microsoft-Windows-WindowsUpdateClient logs (attached) shows an error Event 31 which states Windows Update failed to download an update. I thought maybe it was a network issue but this happens on multiple machines using various different internet connections (corporate and home networks). Running the Windows Update Troubleshooter results in nothing ("Troubleshooting couldn't identify the problem"). Running sfc /scannow shows no issues with the system. Restarts and re-attempts have no impact. I've also included the output from Get-WindowsUpdateLog (timestamps may be different since I captured these on two different attempts). Any thoughts on root cause and solutions are greatly appreciated.
