Hi Folks, I recently upgraded my RH9 box to fc2. When I´m logged in as root or make su - root as a normal user and then run either "yum" or "up2date" I get the following error: Traceback (most recent call last): File "/usr/bin/yum", line 22, in ? import yummain File "/usr/share/yum/yummain.py", line 31, in ? import yumcomps File "/usr/share/yum/yumcomps.py", line 4, in ? import comps File "/usr/share/yum/comps.py", line 5, in ? import libxml2 File "/usr/lib/python2.3/site-packages/libxml2.py", line 1, in ? import libxml2mod ImportError: /usr/lib/python2.3/site-packages/libxml2mod.so: undefined symbol: xmlXIncludeProcessFlags When just making "su" as normal user and then running yum/up2date anything works fine. I already searched google for that but the only hint I got was to check if libxml2 and libxml2-devel should be the same version. This is the case. I also updated to the latest python, libxml2(-devel) packages. # rpm -qa | grep libxml2 libxml2-python-2.6.10-2 libxml2-2.6.10-2 libxml2-devel-2.6.10-2 It´s so strange that the error only occurs when yum/up2date is being run under root. Any help is appreciated! Thanks & Regards, Chris
