Actually, “sudo apt-get install mpich” only installs mpirun and mpiexec, but not mpif90, which is required for OpenCoarrays. This seems very strange, but even if it apt-get installed mpif90, I would need for it to be wrapping a newer version of gfortran than is currently installed by apt-get on Windows 10 Subsystem for Linux.

“sudo apt-get source mpich” yields “E: You must put some ‘source’ URIs in your sources.list.” Adding -b before or after “source” generates the same result.
