Hi, I am trying to bring one of my CentOS 5 VMs up to date. I have run: yum clean all yum update yum yum clean all yum update python* rpm* yum clean all without any problems or error messages. Now when I try to run yum update, I get the following: [root at tusker ~]# 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, 15:37:37) [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 I then downloaded the python-clementtree package from dags site and tried to install it and get: [root at tusker ~]# rpm -i ./python-celementtree-1.0.5-1.2.el5.rf.x86_64.rpm warning: ./python-celementtree-1.0.5-1.2.el5.rf.x86_64.rpm: Header V3 DSA signature: NOKEY, key ID 6b8d79e6 error: Failed dependencies: python-elementtree conflicts with python-celementtree-1.0.5-1.2.el5.rf.x86_64 yet when I query the package I get: [root at tusker ~]# rpm -q python-celementtree-1.0.5-1.2.el5.rf.x86_64.rpm package python-celementtree-1.0.5-1.2.el5.rf.x86_64.rpm is not installed and when I try to remove it I get: [root at tusker ~]# rpm -e ./python-celementtree-1.0.5-1.2.el5.rf.i386.rpm error: package ./python-celementtree-1.0.5-1.2.el5.rf.i386.rpm is not installed I have tried rebuilding the rpm database with no result. Any suggestions? TIA ChrisG
