Source facts

\n

Microsoft warns that a deployment referencing a specific gallery image version can fail if that version is deleted or removed from its region. The generalized-image guide supplies the full image-version identifier when a particular version is required. Microsoft Learn

\n

Applicability

\n

This troubleshooting check applies to Azure VM automation that deliberately uses a specific generalized Azure Compute Gallery image version. The approved version choice is already established; the investigation asks whether that exact source remains available to the deployment.

\n

DSE recommendation

\n

DSE recommends recording the failed request’s full image-version identifier and intended region before changing the deployment. Ask the image owner to compare those values with the current gallery inventory and recent version-retirement or regional-distribution changes. Keep the observed source-availability issue separate from an application startup failure. If the approved version is unavailable, obtain a decision about restoring the required availability or qualifying a replacement before rerunning the pipeline.

\n

Verification

\n

For an authorized retry, confirm that the requested version and region match the remediation decision and inspect the resulting deployment outcome. Retain the original error and source reference so a successful replacement does not erase the cause. Verify the created VM uses the approved image version, and document any remaining deployment failure independently rather than treating every subsequent error as evidence that the same source issue persists.
