PowerEdge: Dell Update Packages may fail to run with an authentication failure error
Summary: Dell Update packages (DUPS) and Inventory collector DUPS in Server update utility fail to run in the Microsoft Windows Operating System (OS).
Symptoms
When a DUP is run in Microsoft Windows OS, it may fail with authentication failure. The issue can occur when the required root CA certificate is not present in the OS Certificate store.
Dell Server Update Utility (DSU) may show no compliance report after it is launched as Inventory collector DUP fails to start.
Cause
The Dell DUPS is signed using a CA certificate, absence of CA cert in the certificate store results in DUP execution failures.
Microsoft Windows Operating systems carry an "Entrust Root Certification Authority (G2)" Certificate in a trusted CA store by default, even if it is deleted, it is recovered by the OS. OS customization may have removed this certificate.
Resolution
CA certificate "Entrust Root Certification Authority G2" is required to be present in Trusted Root Certificate Authorities store in Windows OS for successful execution of DUP in OS.
