InformationYou should verify that the /etc/docker directory ownership and group ownership is correctly set to root.
The /etc/docker directory contains certificates and keys in addition to various other sensitive files. It should therefore be individual owned and group owned by root in order to ensure that it can not be modified by less privileged users.
SolutionTo resolve this issue you should run the following command:
chown root:root /etc/docker
This sets the ownership and group ownership for the directory to root.
By default, the ownership and group ownership for this directory is correctly set to root.
