[chef] Re: chef gem version mismatch?

[AJ Christensen < >]

Hi,

Per the 0.9 notes:

Upgrading to 0.9 from 0.8 is a much smoother transition than from 0.7 to
 0.8, but there are still some pitfalls to be aware of. First of all, 
0.9 chef-clients can read from 0.8 servers, but cannot save to 0.8 
servers. 0.8 chef-clients cannot read from 0.9 chef servers at all, so 
you will need to upgrade your clients and server in lock-step.

Something tells me a 0.9 client will not work as intended (or, as we've seen: at all) with a 0.8.10 server.

Regards,

AJ

I have a client that tries to authenticate with the server, but it gets back a 500 response.

This is what happens on the server side.

I do have a different version of the chef gem on the server and client, but I have lots of client machines with 0.9.0 and they seem to be just fine....

Any thoughts on what might be going on here?

John
