CentOS 5 Yum Update Breakage

[spacejunk]

My yum update no longer works. Every time I try to update, I'm greeted with the following error:

Dependencies Resolved
Traceback (most recent call last):
  File "/usr/bin/yum", line 29, in ?
    yummain.user_main(sys.argv[1:], exit_code=True)
  File "/usr/share/yum-cli/yummain.py", line 309, in user_main
    errcode = main(args)
  File "/usr/share/yum-cli/yummain.py", line 261, in main
    return_code = base.doTransaction()
  File "/usr/share/yum-cli/cli.py", line 362, in doTransaction
    lsts = self.listTransaction()
  File "/usr/share/yum-cli/output.py", line 895, in listTransaction
    self.tsInfo.makelists(True, True)
TypeError: makelists() takes exactly 1 argument (3 given)

Cleaning the yum and RPM databases doesn't fix it.

Any ideas?

did you recently get an update to yum? did you use some other non-official repository to upgrade yum?

Not as far as I know. I have EPEL and PGDG84 enabled as well, but I don't think either of them are the issue.

Check in your /etc/yum.repos.d directory - you may have some .rpmnew files that have not been installed because you have modified repo files.

I had a similar issue with Fedora a few months ago. This resulted in a bug being raised, and they issued a new install of yum. If something like that has happened, it might be possible to fix it by browsing a local CentOS mirror, downloading the yum rpm package and installing it by hand.

No such luck. I have no .rpmnew files. :-/
