Package: libopenmpi1.10 Version: 1.10.3-2 Severity: important Dear Maintainer,
when trying to run the standard mpi petsc test case after compilation, mpiexec gives the following warning: mca: base: component_find: unable to open /usr/lib/openmpi/lib/openmpi/mca_btl_openib: libmca_common_verbs.so.7: cannot open shared object file: No such file or directory According to `dpkg -L', libmca_common_verbs.so.7 should be installed in /usr/lib, however, it bizarrely does not seem to be installed there as verified by a reinstall: $ sudo apt-get install --reinstall libopenmpi1.10 Reading package lists...
