Description Jeff MacDonald 2004-01-07 14:23:43 EST
From Bugzilla Helper:
User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.4.1)

Description of problem:
I logged in as root to do a 'yum upgrade', and I get the following

Gathering header information file(s) from server(s)
Server: Fedora Core 1 - i386 - Base
Traceback (most recent call last):
  File "/usr/bin/yum", line 60, in ?
  File "yummain.py", line 188, in main
  File "clientStuff.py", line 766, in get_package_info_from_servers
  File "clientStuff.py", line 103, in HeaderInfoNevralLoad
ValueError: unpack list of wrong size

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

How reproducible:

Steps to Reproduce:
1. run 'yum upgrade'
2. wait
3. ka-boom

Actual Results:  traceback from python with a ValueError, as noted in

Expected Results:  expected some sort of timeout error, and move on to
next mirror in list.

Additional info:

this problem appears to be triggered while getting headers from the
redhat.com repo. yum crashed before it moved to the mirrors I have
configured /etc/yum.conf with. in my testing, I ran 'yum upgrade' a
2nd time to try to duplicate the problem, and it crashed with the same
traceback after a couple of minutes delay.
Comment 1 Jeff MacDonald 2004-01-07 14:31:55 EST
this appears to be a problem with the redhat.com repo. when I
commented out the appropriate lines in /etc/yum.conf, the upgrade
command runs just fine.
Comment 2 Jeff MacDonald 2004-01-14 18:58:52 EST
I now get this same error when using the 'muohio.edu' repo when using
the 'check-update' command. the 'base' seems to be fine, but the
'updates' is what crashes. same line/function as with the redhat.com repo.

Comment 4 Theodore C. Belding 2004-01-22 14:21:39 EST
I was also getting this error, using the redhat repository as well as
various mirrors. But the config file from
seems to work fine. See also
(although the section about adding multiple "baseurl=" statements for
a single repository seems incorrect -- see the yum.conf man page).
Comment 5 Jeff Johnson 2004-01-25 22:31:44 EST
This problem appears to be transient, i.e. network and/or server
related, not the yum client.
