### Invalid MediaType

**Problem**
|
|
|
|
```
|

Error: error building and pushing "linuxkit/mkimage-iso-efi-initrd:0e66171ffde9bb735b0e014f811f9626fc8b9bc9": PUT https://index.docker.io/v2/linuxkit/mkimage-iso-efi-initrd/manifests/0e66171ffde9bb735b0e014f811f9626fc8b9bc9: MANIFEST_INVALID: manifest invalid; if present, mediaType in image index should be 'application/vnd.oci.image.index.v1+json' not 'application/vnd.docker.distribution.manifest.list.v2+json'
|
|
```
|
|
|
|
The above message is caused by registries, notably docker hub, refusing to accept indexes with the
|
|
docker media type of `application/vnd.docker.distribution.manifest.list.v2+json`, rather than the OCI
|
|
one `application/vnd.oci.image.index.v1+json`.
|
|
|
|
Linuxkit _does_ use the OCI media type, however, if the image _already_ exists in the registry, linuxkit will
|
|
pull the index down, update it, and push it back up. The above error occurs because the index that exists in
|
|
the hub, the one that is pulled down, has the older media type, from when the registry accepted it.
|
|
|
|
**Solution**
|
|
|
|
The solution is to force an entirely new build, which will generate the images and index with the correct media
|
|
type.
|
|
|
|
```
|
|
linuxkit pkg build --force <path>
|
|
linuxkit pkg push <path>
|
|
```
