[Spacewalk-list] rhnreg_ks failure with Python 3 on Fedora 23

Fri Jan 29 20:57:45 UTC 2016

I know Fedora 23 is not officially supported in Spacewalk 2.4, but I
wanted to provide another piece of feedback in my efforts to try to use
the client nightlies for Fedora 23 against a Spacewalk 2.4 server. I am
currently seeing an Internal Server Error when attempting to register
one of my machines (using rhnreg_ks). On the client side, the stack
trace was as follows:

[Wed Jan 27 08:40:37 2016] up2date A protocol error occurred: Internal
Server Error , attempt #1,

    raise e
<class 'up2date_client.up2dateErrors.CommunicationError'>: rhn-plugin:
Error communicating with server. The message was:
Internal Server Error

I looked at the server side and have included its error_log below. What
I believe is happening rhnreg_ks is being run within /usr/bin/python3.
However, as far as I've been able to tell, there is no ethtool package
for python 3 available. I think this causes
up2date_client.hardware.read_network_interfaces() to not return any
NETINTERFACES. I haven't traced through all of the server code, but I'm
suspecting it is this lack of data that is causing an ISE.

While I can work around this by forcing rhnreg_ks to be run with
/usr/bin/python (the 2.7.x version), is there a plan to either get the
ethtool Python package ported to Python 3 or use something different in
the hardware module to resolve the network interfaces prior to the
Spacewalk 2.5 release?

Thanks,
Brian
