InformationYou should verify that the Containerd socket file has permissions of 660 or are configured more restrictively.
Only root and the members of the root group should be allowed to read and write to the default Containerd Unix socket. The Containerd socket file should therefore have permissions of 660 or more restrictive permissions.
SolutionYou should execute the command below.
chmod 660 /run/containerd/containerd.sock
This sets the file permissions of the Containerd socket file to 660.
By default, the permissions for the Containerd socket file is correctly set to 660.
