Hello, Investigating bug #1230838, I noticed that when installing mmg3d-libs, dnf installs Konsole output ptscotch-mpich, whereas yum-deprecated installs scotch. Both scotch and ptscotch-mpich provide the required libscotch.so.0()(64bit), albeit one in /usr/lib64/ and the other one in /usr/lib64/mpich/lib/: $ dnf repoquery --requires mmg3d-libs [...] libscotch.so.0()(64bit) libscotcherr.so.0()(64bit) [...] $ dnf provides 'libscotch.so.0()(64bit)' ptscotch-mpich-6.0.4-2.fc23.x86_64 : PT-Scotch libraries compiled against mpich Repo : rawhide ptscotch-openmpi-6.0.4-2.fc23.x86_64 : PT-Scotch libraries compiled against openmpi Repo : rawhide scotch-6.0.4-2.fc23.x86_64 : Graph, mesh and hypergraph partitioning library Repo : rawhide Konsole output $ dnf repoquery -l scotch.x86_64 | grep libscotch.so.0 /usr/lib64/libscotch.so.0 /usr/lib64/libscotch.so.0.2 Konsole output $ dnf repoquery -l ptscotch-mpich.x86_64 | grep libscotch.so.0 /usr/lib64/mpich/lib/libscotch.so.0 /usr/lib64/mpich/lib/libscotch.so.0.2 $ dnf install mmg3d-libs [...] Installing: environment-modules x86_64 3.2.10-14.fc23 rawhide 117 k hwloc-libs x86_64 1.10.1-2.fc23 rawhide 1.3 M lzma-libs x86_64 4.32.7-13.fc22 rawhide 38 k mmg3d-libs x86_64 4.0.2-1.fc23 rawhide 211 k mpich x86_64 3.1.4-3.fc23 rawhide 1.1 M ptscotch-mpich $ yum-deprecated install mmg3d-libs [...] Installing: mmg3d-libs x86_64 4.0.2-1.fc23 rawhide 211 k Installing for dependencies: lzma-libs x86_64 4.32.7-13.fc22 rawhide 38 k scotch So, whose fault is this? Packaging of dnf? Nothing relevant for this caught my eye skimming through the packaging guidelines. And related: trying to install some $pkg-openmpi package, I don't generally see packages enforcing that the -openmpi version of some dependency library is installed as opposed to just the regular libs package. Should such requires need to be stated explicitly?
MPI packages need to filter out the provides from the MPI versions and explicitly add needed requires on the specific MPI flavors of packages needed. This probably needs to be added to the MPI guidelines.
