Solution
Step 1- Find out the file location-
systemctl show -p FragmentPath docker.service
Step 2- If the file does not exist, this recommendation is not applicable. If the file exists, execute the below command with the correct file path to set the ownership and group ownership for the file to 'root'.
For example,
chown root:root /usr/lib/systemd/system/docker.service
Impact-
None.
Default Value-
This file may not be present on the system. In that case, this recommendation is not applicable. By default, if the file is present, the ownership and group-ownership for this file is correctly set to 'root'.
