So I've been following http://www.devops-blog.net/category/spacewalk ... 
creating my own server and client cookbooks.
Everything was working perfectly when I left the office before last Friday; 
Systems registering, Gpg signed, package updates...

While my Precise 12.04 systems are still working, doing and "apt-get update" on 
the Trusty systems results in the following error...

Ign spacewalk://SPACEWALK-URL trusty InRelease
E: Invalid message from method spacewalk: SSL exception (-1, 'Unexpected EOF')
102 Status
Message: Waiting for headers
URI: spacewalk://SPACEWALK-URL/dists/trusty-security/InRelease

I have tried removing and adding a client, I've tried recreating the Release 
files on the server for the Trusty channels.

I know the error is defined in  "/usr/lib/apt/methods/spacewalk" ...
Contents of file below.

Can someone point me in the right direction please?
