Extension failing in Linux VM

Hi,

I am trying to install the KeyVaultForLinux (4.x) extension on an Ubuntu 24.04 VM, but I am encountering an issue during deployment.

Environment Details:

Using the VM's Managed Identity for authentication.

The Managed Identity already has the required access permissions to the Azure Key Vault (AKV)

Issue: The deployment fails during the certificate and private key validation step. The error indicates a certificate/key mismatch.

However:

The certificate stored in the Key Vault is valid and has been in use for a long time without any issues.

The certificate was originally uploaded to the Key Vault as a PFX.

Manual validation of the certificate and private key does not show any mismatch.

Other services using the same certificate have been working successfully. (Ex: AppGW is using cert from AKV)

Since the certificate can be retrieved successfully but the validation fails only within the KeyVaultForLinux extension, I would like to understand: any similar issue has been identified?

Any guidance would be greatly appreciated.

Error: failed with exception: InitFromPEM: Mismatched X509 and private key.: error:05800074:x509 certificate routines::key values mismatch
