Description Ed Solis 2005-07-17 21:28:34 EDT
From Bugzilla Helper:
User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.7.8) Gecko/20050524 Fedora/1.0.4-4 Firefox/1.0.4

Description of problem:
When I run yum update, it sometimes fail with an IndexError: list index out of range. I think it errors when trying to locate a mirror server. It doesn't happen every time though.

This is on a newly installed FC4 system. I'm also behind a proxy server. The proxy server needs authentication. 

Version-Release number of selected component (if applicable):

How reproducible:

Steps to Reproduce:
I executed the following command as root:

1. export http_proxy=http://username:password@proxy.example.com:3128/ (not actual user/password/proxy names)
2. yum update

Actual Results:  Sometimes yum runs successfully but most of the time it generates a traceback. The error is always an IndexError: list index out of range. 

Expected Results:  yum should run successfully without generating a traceback.

Additional info:

 When I run yum update, I have encountered the same phenomenon above.
I re-install yum package, but in vain.
 In adition, my versions of yum and python packages are the same above. In 
spite I don't use a proxy server, I encountered the same phenomenon above.
 Please tell me how to solve this problem.
