I got the same problem in a X86_64 platform. Trying to reconfigure manually I got :
dpkg --configure -a Configurando openmpi-bin (1.3.2-3ubuntu1) ... update-alternatives: error: alternativa mpiexec não pode ser principal: é uma dependência de mpirun dpkg: erro processando openmpi-bin (--configure): sub-processo script post-installation instalado retornou estado de saída de erro 2 (Ok, it is portuguese but reads : Configuring openmpi-bin (1.3.2-3ubuntu1) ... update-alternatives: error: alternative mpiexec cannot be principal: is a dependency of mpirun dpkg: error processing openmpi-bin (--configure): sub-process script post-installation instaled returned output state error 2 ) The symlink "/etc/alternatives/mpiexec" pointed to LAM mpiexec. Removing LAM packages solved the problem. My suggestoin is that OpenMPI and LAM should conflict to avoit this kind of error. -- package openmpi-bin 1.3.2-3ubuntu1 failed to install/upgrade: subprocesso installed post-installation script retornou erro do status de saída 2 https://bugs.launchpad.net/bugs/447271 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
