Murano

Issue while deploying murano package on ubuntu 16.04

Asked by Anjali Pathak

I am deploying murano package using ubuntu 16.04. When we are deploying murano packages, the murano agent gets installed inside the guest vm(instance) however the deployment fails while throwing an error ("ImportError: No module named builtins") inside the guest vm.

please refer the below logs.

Hi, Anjali, first of all, thanks for use murano, I checkout this problem, I want to know the 'GitPython' version in your guest vm, As the upper-constraints.txt(https://github.com/openstack/requirements/blob/master/upper-constraints.txt#L541), in python2.7, the GitPython should be 2.1.11, But as the error log you paste, I check the GitPython code, I think your use the high verion not suiteable in python2.7. Please downgrade the GitPython to 2.1.11, and have a try. thanks

Dear Zhurong,

Thank you for your valuable guidance.
Yes, you are right the GitPython version which I had in my Guest VM was high and not supported by the python2.7. After downgrading the version of GitPython to 2.1.11, I am able to solve the problem which I have been facing earlier.

But now, I am facing an another issue after downgrading the version.
Please refer the below logs:

You mark this as sloved, I thougt you deploy succesfully.
As the log, maybe your guest vm cann't connect with the rabbitmq-server. please verift your vm can connect with your controller rabbitmq-server.

As per our observation we also analyse that this occur due to guest vm cann't connect with the rabbitmq-server. i am not able to ping or telnet rabbitmq server. currently we are looking on it.
