I followed the procedures at https://fedoraproject.org/wiki/Upgrading_Fedora_using_yum#Fedora_17_-.3E_Fedora_18 and after a reboot, updated my sagemath x86_64 repository. I had a few f15 plexus&maven packages that appeared to cause upgrade problems as well as ffmpeg-libs, but this was enough for me to convert a f17 computer to f18: $ sudo yum erase sagemath $ sudo yum erase plexus-appserver plexus-runtime-builder plexus-maven-plugin maven-shared plexus-xmlrpc ffmpeg-libs $ sudo yum update yum $ sudo yum clean all $ sudo yum --releasever=18 --disableplugin=presto distro-sync $ sudo rpm --rebuilddb If you previously had a /etc/yum.repos.d/sagemath-f17.repo, please now use http://pcpa.fedorapeople.org/sagemath/sagemath-f18.repo There is a Singular update, but the same build should be available as an update in a few days https://admin.fedoraproject.org/updates/Singular-3.1.5-3.fc18 and I just opened a bug report to update f18 to the same numpy in rawhide https://bugzilla.redhat.com/show_bug.cgi?id=896311 Thanks, Paulo _______________________________________________ scitech mailing list scitech@xxxxxxxxxxxxxxxxxxxxxxx https://admin.fedoraproject.org/mailman/listinfo/scitech
