I stumbled across this issue because I requested to install the sysreport package in my kickstart file. Anaconda complains that such a package doesn't exist. There is a bug report about this already (http://bugs.centos.org/view.php?id=2492), but it's certainly a strange situation. 1. Anaconda doesn't think the package sysreport exists 2. yum thinks it exists: # yum list sysreport Loading "installonlyn" plugin Setting up repositories Reading repository metadata in from local files Available Packages sysreport.noarch 1.4.3-13.el5 base 3. But installing with yum fails: # yum install sysreport Loading "installonlyn" plugin Setting up Install Process Setting up repositories Reading repository metadata in from local files Parsing package install arguments Package sos - 1.7-9.1.el5.noarch already installed and latest version Nothing to do 4. The sysreport file from the sos package fails to run: # sysreport Traceback (most recent call last): File "/usr/sbin/sysreport", line 31, in ? import sos.policyredhat ImportError: No module named sos.policyredhat 5. But if you extract /usr/sbin/sysreport from the sysreport package using rpm2cpio for instance, it works just fine. So it would be nice if yum would allow installing the sysreport package (see step 3 above) as that would appear to solve all the problems. Alfred
