koan --update-config ??

[Brainslugongithub]

Looking into the CMS part of cobbler right now. Running two physical servers, both Scientifc Linux 6.3 (64bit), cobbler commit 8388a2a660.
My client seems to be able to communicate w/ the server:

[root@test1 tmp]# koan --server=10.2.9.7 --display --system=test1

    virt_auto_boot  : 0
     virt_pxe_boot  : 0
  [root@test1 tmp]# 

but I can't do any updates:

[root@test1 tmp]# koan --server=10.2.9.7 --update-config

    raise Fault(**self._stack[0])
  Fault: <Fault 1: "<type 'exceptions.AttributeError'>:'NoneType' object has no attribute 'get_parent'">

Any idea what might be going wrong here?

Thanks much!

Issue list cleanup: this is an old issue, probably on an old cobbler version. If this is still an issue for you on a recent cobbler let me know and i will re-open this issue.

I'm running into a little trouble getting Koan to work with Cobbler and I was hoping that you might be able to point me in the right direction to get it fixed.

When using koan's --update-config option to try and pull down some configuration files I ran into the exact same issue seen on github here https://github.com/cobbler/cobbler/issues/555. I tried to do a list cleanup with no success. I didn't want to try and open the ticket since you mentioned it was an old issue but since I'm running the latest Cobbler (2.6.1) and Koan (2.4.4) I thought I'd contact you.

Is there anything I can check to see if the issue is simply a mis-configuration or damaged install? I've tried to pull down the latest cobbler-2.6.1.tar.gz from https://github.com/cobbler/cobbler/releases/tag/v2.6.1 and ran a make webtest but it errored with the following message.

bin/sh: -c: line 2: syntax error: unexpected end of file
make[1]: **\* [restorestate] Error 1
make[1]: Leaving directory `/root/cobbler-2.6.1'
make: **\* [devinstall] Error 2

Afterwards Koan is still encounters the same error. Any advice you could provide would be greatly appreciated.

Sincerely,

Caleb Moniot
