Hello,

I am on Centos 6.2 and when trying to run the ansible command i am  
getting crypto errors. Anyone hit this issue before?

[root@dev-m01 ansible]# python -V  
Python 2.6.6  
[root@dev-m01 ansible]# cat /etc/redhat-release  
CentOS release 6.2 (Final)  
[root@dev-m01 ansible]#

ansible all -m ping --ask-pass

Thanks for posting here.

Yeah as I replied on the github ticket, I am developing on CentOS 6.2 + EPEL and haven’t seen this. Curious if others have and what may be special  
about configurations and environments.

Is there a way to confirm the package versions needed for ansible  
(crypto, jinja2, etc) ?

This is my crypto version, is yours the same ?

# yum list | grep python | grep crypto  
python-crypto.x86\_64  
2.0.1-22.el6 @base

I’m strongly against hard dependencies for such things when we don’t have a reason for specific deps.

Exact same version here.

python-paramiko is 1.7.5-2.1.el6  
python.i686 2.6.6-29.el6

No other modules installed outside of RPM, etc?

If you haven’t done anything you remember, it’s probably normal 🙂

any chance it has to do with the version of ssl ?

openssl.i686  
1.0.0-20.el6\_2.4 @update  
openssl.x86\_64  
1.0.0-20.el6\_2.4 @update  
openssl-devel.x86\_64  
1.0.0-20.el6\_2.4 @update
