Some host extension remediation or staging operations fail because Update Manager does not automatically download and install missing prerequisites.


Host extension remediation or staging might fail.


Update Manager skips the extensions with missing prerequisites and lists the missing prerequisites as events when it detects them during the staging and remediation operations. To proceed with staging and remediation, you must install the prerequisites.


  1. To see which prerequisites are missing, in Compliance View select Tasks & Events > Events.
  2. Add the missing prerequisites manually to either an extension or a patch baseline, depending on the type of the missing prerequisites.
  3. (Optional) Create a baseline group that contains the new baseline as well as the original baseline.
  4. Remediate the host against the two baselines.
