So far, I could not find the related “problematic asset” and assign it to a specific blob on the file system. Now I run the job `Repair - Reconcile componen database from blob store` I hoped the job would help an solve the issue. It didn’t my initial job `Delete unused manifests and images` still dont work. But The reconcile job printed the blob ID on the file system. Now my big question. Is it safe to delete those blobs on the file system level? Output from the reconcile job: `*SYSTEM com.sonatype.nexus.blobstore.restore.internal.datastore.DockerRestoreBlobStrategy - Skipping as asset already exists, blob store: default, repository: docker-hosted, path: /v2/-/blobs/sha256:098cb24285eb179125c9118cab8b75f60edb80c3f0b23a160a4d79d8f8fa91a3, blob name: /v2/-/blobs/sha256:098cb24285eb179125c9118cab8b75f60edb80c3f0b23a160a4d79d8f8fa91a3, blob id: 5e1e0482-22ef-4d5c-8ff0-df6d6da2cfc7` With the blob ID I was able to find them: ```auto find ./* -name "*5e1e0482-22ef-4d5c-8ff0-df6d6da2cfc7*" ./blobs/default/content/vol-13/chap-30/5e1e0482-22ef-4d5c-8ff0-df6d6da2cfc7.properties ./blobs/default/content/vol-13/chap-30/5e1e0482-22ef-4d5c-8ff0-df6d6da2cfc7.bytes ``` Any opinions? Or did someone already tried it? --- _[View the full topic](https://community.sonatype.com/t/failed-task-delete-unused-manifests-due-to-invalid-asset/13597)._
