I think you may have installed some different program also called "mirage". Make sure you don't have any distribution-provided package by that name (e.g. "apt-get purge mirage") and install mirage through opam: opam install mirage (see https://mirage.io/wiki/install) > Out of curiosity, is there a preferred distro for dev/testing?
