Comment 3 for bug 1874645

It happens to me during the upgrade of Ubuntu 20.04 LTS to Ubuntu 22.04 LTS. My system has installed openmpi-bin (4.1.2-2ubuntu1).

A had run the pre-removal script manually with following result:

  $ sudo sh -x /var/lib/dpkg/info/openmpi-bin.prerm remove
  + set -e
  + [ remove = remove ]
  + update-alternatives --remove mpirun /usr/bin/mpirun.openmpi
  + update-alternatives --remove mpi /usr/bin/mpicc.openmpi
  update-alternatives: error: /var/lib/dpkg/alternatives/mpi corrupt: slave link same as main link /usr/bin/mpicc

[That solution](https://stackoverflow.com/questions/62464085/openmpi-bin-error-after-update-kubuntu-18-04-to-20-04) fixes the situation
