I just removed the i686 packages with rpm -ev mesa-dri-drivers-7.11-1.fc15.i686 mesa-dri-llvmcore-7.11-0.11.20110525.0.fc15.i686 llvm-libs-2.8-12.fc15.i686 then yum update could proceed, and now all my packages are up to date. Then "yum check" only reported one remaining problem: chess-1.0-37.fc15.x86_64 has missing requires of libboost_thread-mt.so.1.46.0()(64bit) The "chess" package doesn't appear to be in F16 at all -- perhaps that's what is now called "gnuchess" ? I just removed the chess package with "rpm -ev chess" So as of now, everything looks updated and clean. (I'll deal with Acrobat reader later, if I ever need it to work again) Thanks again for your help. -- Deron Meranda http://deron.meranda.us/ -- users mailing list users@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe or change subscription options: https://admin.fedoraproject.org/mailman/listinfo/users Guidelines: http://fedoraproject.org/wiki/Mailing_list_guidelines
