description: """
A formalisation of Burali-Forti paradox in system U (the
existence of an ordinal of ordinals is inconsistent), of Diaconescu
paradox (axiom of choice implies excluded-middle), of Reynolds paradox
(there is no set-theoretic model of system F) and Hurkens paradox in
system U (adapted by H. Geuvers to show the inconsistency of
Excluded-Middle in impredicative-Set Calculus of Inductive Constructions)."""

Dry install

Dry install with the current Coq version:

Command
opam install -y --show-action coq-paradoxes.8.9.0 coq.dev
Return code
5120
Output
[NOTE] Package coq is already installed (current version is dev).
The following dependencies couldn't be met:
  - coq-paradoxes -> coq < 8.10~ -> ocaml < 4.10
      base of this switch (use `--unlock-base' to force)
Your request can't be satisfied:
  - No available version of coq satisfies the constraints
No solution found, exiting

Dry install without Coq/switch base, to test if the problem was incompatibility with the current Coq/OCaml version:

Command
opam remove -y coq; opam install -y --show-action --unlock-base coq-paradoxes.8.9.0
