[K12OSN] CentOS 6.2 LTSP setup

[David C. Moody]

Hi Everyone,

I'm currently using an Ubuntu LTSP setup, that works well however it's time to upgrade hardware and I'm having trouble getting Ubuntu to install now.

Anyway,  I installed CentOS 6.2 then followed the K12Linux setup instructions and I continue to fail during the ltsp-build-client process.

Below is the error message I receive, any help would be greatly appreciated.

Retrieving http://mirror.ancl.hawaii.edu/linux/scientific/6.1/i386/updates/security/repodata/repomd.xml ...OK
/usr/lib/python2.6/site-packages/imgcreate/errors.py:40: DeprecationWarning: BaseException.message has been deprecated as of Python 2.6
