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
Is python-rpm installed?
