Hi, I have upgraded Centos from 3.x to 4.3.
The upgrade apparently didn't go too bad. I had to do the upgrade remotely, and I used as a base the post at http://www.centos.org/modules/newbb/viewtopic.php?topic_id=382
I rebooted the server, and it works. But yum does not work anymore, apparently due to some conflict between rpmlibs and selinux.
This is the error that I get:
--------------------------
There was a problem importing one of the Python modules required to run yum. The error leading to this problem was:
/usr/lib/python2.3/site-packages/rpmmodule.so: undefined symbol: rpmtsSetREContext
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: 2.3.4 (#1, Feb 22 2005, 04:09:37) [GCC 3.4.3 20041212 (Red Hat 3.4.3-9.EL4)]
--------------------------
These are the relevant rpms that I have installed in my system: python-2.3.4-14.1 rpm-4.3.3-13_nonptl rpm-libs-4.3.3-13_nonptl yum-2.4.2-2.centos4
any suggestion?
Thanks in advance, Andres

Is python-rpm installed?

Hi, if you mean rpm-python, yes. I haven't a package called python-rpm.
I have rebooted with selinux enabled as permissive and yum it's not working either. Before it was set up as disabled.

Yes, I did. I even double checked it on my system and still typed it wrong...
I have rpm-python-4.3.3-18_nonptl installed.

I don't think your error has anything to do with SELinux, per se.

ldd /usr/lib/python2.3/site-packages/rpmmodule.so
tell you?
And now you know why upgrades between major versions are not supported ;-)

Hi Matt, upgrading rpm-python to your version (alog with the other rpm* packages) made it work. Thanks!
I know that it's not suggested to upgrade but I was getting stuck with old packages all the time. It took time, but finally is (mostly) sorted (apart from a few warnings that I'm still trying to track).
Thanks again,
Andres

IMHO enabling SELinux usually doesn't FIX any problems, although it might CAUSE some. ;-) It sounds as though you have some rpm leftovers from the old install. This is why it is advised against doing major version upgrades.

Update
rpm-python
package accordingly as well. You will have to grab it by hand off a mirror and update with rpm -Uvf <packagefile>.
