4 years ago Hi @distsystemsarchitect , The error seems to be because of some updated cryptography package here. I suggest you uninstall it using below command on both controller and node. pip uninstall -y cryptography
Run the deploy script after removing it. If you face this error again, please install watchdog on both node and controller and run the below command parallelly while running the deploy_ne.sh script. watch pip uninstall -y cryptography
Basically this command will be executed every 2 seconds, so if by any chance cryptography get installed anytime during the installation process, using watchdog will keep on clearing it automatically without manual intervention. Please let us know if this works.

While trying to run the deploy scripts (deploy_ne.sh), I am getting errors of version compatibility of python. This is on a clean install of Centos on KVM. Full connectivity between controller node and edge node (tested with ansible -m ping all command).
I am getting the following error: STDOUT:

Additionally, this renders my ansible installation unusable, even if I remove and install again (yum remove / install ). I have tried updating python to later versions, but then get other syntax errors).
