Hi @Chandan_Chatterjee, welcome to the board!

I see you ran into a provisioning error, but we’re going to need a bit more context to be able to help you. What version of Open edX are you trying to install? Do I presume correctly that you’re following the native installation document?

HI @arbrandes

I am trying to install open-release/juniper.1 And yes i am using. https://openedx.atlassian.net/wiki/spaces/OpenOPS/pages/146440579/Native+Open+edX+platform+Ubuntu+16.04+64+bit+Installation

Try with new release juniper.2

I am using juniper.2 and also tried with juniper.master

Ansible does not run and I get the message

Ansible failed!

Decoded error:
No message to decode.

in the logs

If you all have any ideas please let me know.

One more question. Could it be because I do not have a domain. In the config.yml, I use my server public IP address instead of domain name for the LMS and CMS base address.
