I'm getting closer, but am still having problems... I manually and selectively ran yum updates to all those packages that didn't cause errors, and so I have now successfully updated most things. Only the following packages still needing updated are *stuck* where I can't proceed: libmtp.x86_64 1.1.1-1.fc16 llvm-libs.i686 2.9-4.fc16 mesa-dri-drivers.i686 7.11-8.fc16 Those won't update because of the following unresolvable dependencies: libmtp = 1.0.6-5.fc15 is needed by (installed) libmtp-hal-1.0.6-5.fc15.x86_64 mesa-dri-filesystem(x86-32) is needed by mesa-dri-drivers-7.11-8.fc16.i686 And "yum check" is now down to just these items: chess-1.0-37.fc15.x86_64 has missing requires of libboost_thread-mt.so.1.46.0()(64bit) libmtp-hal-1.0.6-5.fc15.x86_64 has missing requires of libmtp = ('0', '1.0.6', '5.fc15') libnih-1.0.2-4.fc15.x86_64 has missing requires of libc.so.6(GLIBC_PRIVATE)(64bit) llvm-libs-2.9-4.fc16.x86_64 is a duplicate with llvm-libs-2.8-12.fc15.i686 mesa-dri-drivers-7.11-1.fc15.i686 has missing requires of mesa-dri-filesystem(x86-32) mesa-dri-drivers-7.11-8.fc16.x86_64 is a duplicate with mesa-dri-drivers-7.11-1.fc15.i686 mesa-dri-llvmcore-7.11-0.11.20110525.0.fc15.i686 has missing requires of mesa-dri-filesystem(x86-32) The suggestion to run "package-cleanup --cleandupes" now does nothing, because there are no duplicates. The "yum distro-sync" fails because of the libmtp-hal dependency. I don't really know what those packages are or what to do about them.
