Hello @KamProjectLead 

It seems a problem connecting your repo URL. Please check if the repo is enabled and the base URL is accessible from docker. 

If the network connection is working well and URL is accessible, just run "yum update all" and run the wizard again as suggested here  - https://github.com/dorianbg/kerberos-on-cloudera-quickstart
