How reproducible:

Steps to Reproduce:
1.run "yum -y update {some package}" or "yum list updates"
Actual results:
Updating yum-metadata-parser.x86_64
Traceback (most recent call last):
  File "/usr/bin/yum", line 29, in ?
  File "/usr/share/yum-cli/yummain.py", line 105, in main
    result, resultmsgs = base.doCommands()

    return self.yum_cli_commands[self.basecmd].doCommand(self, self.basecmd, 
  File "/usr/share/yum-cli/yumcommands.py", line 163, in doCommand
    return base.updatePkgs(extcmds)
  File "/usr/share/yum-cli/cli.py", line 601, in updatePkgs
    updates = self.up.getUpdatesTuples()

  File "/usr/lib/python2.4/site-packages/yum/packageSack.py", line 226, in

Expected results:
Yum should just work.

 Imported varient of fix (though not know about at the time). Just need some flags.
Comment 5 Petr Sklenar 2008-04-17 08:07:04 EDT
1.run "yum -y update {some package}" or "yum list updates"
2. if yum works PASS
else FAIL


I couldnt reproduce it, I tried update many packages, there should be some
combination of various version of yum, or yum-metadata-parser. Could someone
verify that bug on fenlason-desk.boston.devel.redhat.com ?? 
Comment 6 James Antill 2008-04-17 10:12:18 EDT
 Right it was a bug in an early yum-3.2.8 version (see comment #0) ... not in
our 3.0.1 version from GA. You can probably get the old version out of the build
system, if you want to make sure.
Comment 9 James Antill 2008-04-21 10:31:54 EDT
 Ok, cool thanks Petr ... that looks about the right version.
