Hi ralf,

Thanks - but I think that is what I have done, have I misunderstood this?

[jeremy@localhost laptops]$ opam switch
#   switch                      compiler                    description
     ocaml-base-compiler.4.02.3  ocaml-base-compiler.4.02.3
           ocaml-base-compiler.4.02.3
->  with-coq                    ocaml-base-compiler.4.05.0  with-coq
[jeremy@localhost laptops]$ opam repo add coq-released 
https://coq.inria.fr/opam/released
[ERROR] Repository coq-released is already set up and points to
         http://coq.inria.fr/opam/released. To change that, use 'opam 
repository
         set-url'.
[jeremy@localhost laptops]$ opam search coq-stdpp
# Packages matching: match(*coq-stdpp*)
# No matches found
[jeremy@localhost laptops]$

Cheers,

Jeremy
