Hello all, I've been googling and haven't found an answer. I have a Centos 4.6 box that is having an issue since the last yum update. The nss_ldap and kernel packages were the only packages installed/updated. When I try to run yum I now receive: [root at ns1 ~]# yum update There was a problem importing one of the Python modules required to run yum. The error leading to this problem was: /usr/lib/librpmdb-4.3.so: undefined symbol: xdr___db_get_name_reply[rpmdb 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, Dec 11 2007, 05:27:57) [GCC 3.4.6 20060404 (Red Hat 3.4.6-9)] If you cannot solve this problem yourself, please go to the yum faq at: http://wiki.linux.duke.edu/YumFaq [root at ns1 ~]# rpm -qi rpm-libs Name : rpm-libs Relocations: (not relocatable) Version : 4.3.3 Vendor: CentOS Release : 23_nonptl Build Date: Sat 17 Nov 2007 06:13:56 AM CST Install Date: Mon 07 Jan 2008 11:57:33 AM CST Build Host: builder6 Group : Development/Libraries Source RPM: rpm-4.3.3-23_nonptl.src.rpm Size : 1739984 License: GPL Signature : DSA/SHA1, Sun 18 Nov 2007 02:55:20 PM CST, Key ID a53d0bab443e1821 Summary : Libraries for manipulating RPM packages.
