getting crypto errors. Anyone hit this issue before?

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

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.

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

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?

not sure how do i tell ?

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

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
