salt: salt ssh error with debian 7 on target

salt-ssh and 2 targets ( debian 7 and debian 8 )

salt-ssh ‘*’ -r ‘ifconfig’ = works well with both targets

salt-ssh ‘*’ cmd.run ‘ifconfig’

This command works well with debian 8. But with debian 7 (wheezy) :

I’m having the same issue on an Ubuntu 12.04 machine using latest salt-ssh release on Debian Jessie. It’s the only target it fails on - even after deleting /tmp/.$USER_$RANDOM_salt - so it might be a good machine to debug this issue on. I can also say, that it’s not the only Ubuntu 12.04 target I have and it works fine on those other ones.

Correct steps to reproduce issue.

Install Debian 8 from Salt repo
Fill roaster file and run command salt-ssh ‘*’ test.ping
You get error ImportError: No module named backports.ssl_match_hostname
Check content of /var/cache/salt/master/thin/thin.tgz /usr/lib/python2.7/dist-packages/salt/utils# tar -tzf ~/thin.tgz | grep back

Expected result: backports module in /var/cache/salt/master/thin/thin.tgz

As workaround you can install package: aptitude install python-backports.ssl-match-hostname and remove already generated /var/cache/salt/master/thin/thin.tgz After that rerun command: salt-ssh ‘*’ test.ping and it completed successfully. gs-host0: True

Also check thin.tgz content: tar -tzf /var/cache/salt/master/thin/thin.tgz | grep back backports/init.py backports/ssl_match_hostname/init.py
