If you get the following error when running 'docker pull':
operator@rp00:~$ docker pull httpd:2.4.65
2.4.65: Pulling from library/httpd
mediaType in manifest should be 'application/vnd.docker.distribution.manifest.v2+json' not 'application/vnd.oci.image.manifest.v1+json'
operator@rp00:~$
I have solved it on Ubuntu 18.04.3 LT by running the following sequence of commands that have not updated the version or build of docker-ce but have installed packages (among them docker-ce-rootless-extras and others) and updated others (containerd.io, docker-ce and libseccomp2) that were apparently required and have solved the problem.
First I executed a:
sudo apt-get update
I then ran the following command which informed me that a number of packages would be installed and updated, and that I accepted the installation:
sudo apt-get install docker-ce --only-upgrade
Output of this command:

The version and build of Docker that I had and that I maintain is the following:
operatordocker@rp01:~/dockerfiles/httpd24ghost$ docker -v
Docker version 19.03.4, build 9013bf5
And when I run 'docker pull' it works now:
operator@rp00:~/dockerfiles/httpd24ghost$ docker pull httpd:2.4.65
