Briefly, this error occurs when Elasticsearch fails to complete the deletion of a snapshot. This could be due to insufficient permissions, a corrupted snapshot, or issues with the underlying storage system. To resolve this, you can try the following: 1) Check and adjust the permissions of the Elasticsearch user to ensure it has the necessary rights to delete snapshots. 2) If the snapshot is corrupted, you may need to manually remove it from the snapshot repository. 3) Investigate the health of your storage system, as hardware issues can also cause this error.
