This is due to a necessary constraint blacklisting Coq >= 8.7 for Frama-C 16 Sulfur, otherwise Frama-C won't compile.

The way opam works is that, when it cannot solve a constraint, it will try in several ways, including downgrading existing packages, as in your case.

We have no direct control over the process. This Stack Overflow question has some suggestions, but they do not always work:


Anyway, with the just released Frama-C 17 Chlorine, the constraint is no longer there, so you should be able to install both Coq 8.8 and Frama-C:

opam update
opam install frama-c.20180501
