I am having problems performing an update to a server with windows server 2019 and I am getting this error (2024-04 Cumulative Update for Windows Server 2019 (1809) for x64-based Systems (KB5036896) - Error 0xca00a000)
Please read .... Windows Update Forum Posting Instructions .... (which you should already have done) .... and then post the required information, so that we can assess your problem.
An error code on its own really doesn't tell us much that is of any use.
