The easiest way to fix this is by putting the layer back into this folder. We can do a checksum search https://www.jfrog.com/confluence/display/JFROG/Artifactory+REST+API#ArtifactoryRESTAPI-ChecksumSearch

Then if found, we can copy it into where it is supposed to be - the folder where the other layers exist. In my example, this would be under docker-local/library/ubuntu/sha256__7b3e30… note that this is not the ‘20.04’ folder. Note that the file name should be in docker layer format (sha256__<sha256 here>), and it has an attached property that is equal to sha256:<sha256 value>.
If it does not exist in your Artifactory, then the image will have to be re-pushed into Artifactory from another source. If it is a public image, this will be as simple as re-caching it via a remote repository, then copying it into your local. Otherwise, you will need to locate the private source of the image and push it back into Artifactory.
