$ sudo rpm -e yum

I'm going in loops here, what am I missing?

Edit-
Here is the command I was looking for:
$ sudo rpm -e yum yum-rhn-plugin rhn-client-tools rhn-check rhn-setup rhnsd

Don't mean to open an old thread but rather than start a new one....

I am having this same issue. I removed all the yum rpms and the python-elementtree python-sqlite python-urlgrabber

then reinstalled them from the rpms on http://rpm.pbone.net but I am still getting this error

Code:

root@server yum-rpm]# yum update
There was a problem importing one of the Python modules
required to run yum. The error leading to this problem was:

   No module named cElementTree

Please install a package which provides this module, or
verify that the module is installed correctly.

It's possible that the above module doesn't match the
current version of Python, which is:
2.4.3 (#1, Sep  3 2009, 15:37:12) 
[GCC 4.1.2 20080704 (Red Hat 4.1.2-46)]

If you cannot solve this problem yourself, please go to 
the yum faq at:
  http://wiki.linux.duke.edu/YumFaq

Can anyone help me out?

thanks

My solution was to rollback to an earlier version of python-elementtree. If you run the following command you can see which packages were most recently updated. You may want to pipe it to less or another pager.

Code:

rpm -qa --last

What I noticed was that python-elementtree was updated in the recent installs. Comparing that to other RHEL 5 systems, it was a version newer than what I had running with the same version of yum elsewhere. So I decided to rollback to the previous version, the same version on other RHEL 5 systems.

First, you need to download the previous version RPM. I obtained python-elementtree-1.2.6-5 from CentOS RPMs as CentOS is Red Hat with the branding removed and some customized packages. I figured the RPM would suffice.

In order to install an older version of a package over a newer one, use the --oldpackages flag with the install command:

Code:

rpm -ivh --oldpackage python-elementtree-1.2.6-5.x86_64.rpm

Then I verified that I had the python-elementtree package installed that I wanted. The 1.2.6-7 package was still there, along with the 1.2.6-5. So I removed the 1.2.6-7 package.

Code:

rpm -e python-elementtree-1.2.6-7.el4.rf

Then I verified that only the version of python-elementtree wanted was installed.

Code:

[tmp]# rpm -qi python-elementtree

Summary     : Fast XML parser and writer
Description :
The Element type is a simple but flexible container object, designed
to store hierarchical data structures, such as simplified XML
infosets, in memory. The element type can be described as a cross
between a Python list and a Python dictionary.

This package also includes the C implementation, cElementTree-1.0.5-20051216.

Lastly, I verified that yum was still working.

Code:

# yum list updates
Loaded plugins: rhnplugin, security
Skipping security plugin, no data

Basically, any yum command could be used, even a simple, yum --version would suffice.

All extraneous repos in /etc/yum.repos.d/ were also set to disabled, enabled=0 because this the newer, unwanted package was obtained from one of them, not the RHN satellite server.
