Briefly, this error occurs when Elasticsearch fails to delete a snapshot due to reasons like the snapshot is currently in use, the snapshot or the repository doesn’t exist, or due to insufficient permissions. To resolve this, ensure the snapshot isn’t in use or being created, verify the snapshot and repository exist, and check if you have the necessary permissions to delete the snapshot.
