fatal: [localhost]: FAILED! => {"msg": "The task includes an option with an undefined variable. 
The error was: 'dict object' has no attribute 'md5'\n\nThe error appears to have been in 
  line 5,   Column 

 3, but may\nbe elsewhere in the file depending on the exact syntax problem.\n\nThe offending 
   line appears to be:\n\n\n- set_fact:\n  ^ here\n"}
        to retry, use: --limit @/opt/bahmni-installer/bahmni-playbooks/all.retry

@lovely- Can you try becoming root and running bahmni install again?

On the command line, run:

sudo su

…and then

bahmni install

Also, check the downloaded java file size under /opt/


cd /opt/

and then

ls -ahl

The output should be similar to this
