Installing why3 fails on docker image

Ecosystem

Hello,

I have been trying to install Why3 within a docker image. The base system is Debian buster-slim. The error I get is the following:

[ERROR] The sources of the following couldn’t be obtained, aborting:
- dune.2.7.1: Could not extract archive
- stdlib-shims.0.1.0: Could not extract archive

Other packages required for Why3 seem to install successfully, but not these two. The same installation works on a standalone Debian of the same kind.

Any help is highly appreciated.

We are building and deploying an image of Why3 built on top of Debian buster-slim during our continuous integration. I don’t remember ever encountering your issue. Here is our Dockerfile, in case it helps:

Hello,

Thank you for your message. I see that you use ocaml from Debian repository. I tried to install everything using opam.

I assume that with this “COPY --chown=guest:guest . /home/guest/why3” you copy and then compile the sources of why3.

I will probably need to follow your approach also.

I just tried it with opam in Docker and it worked for me. Here are the commands I used:

$ docker run --rm -it ocurrent/opam:debian-10-ocaml-4.11
opam@e6b8ea03ff81:~$ opam depext -i why3
[...]
-> installed why3.1.3.3
Done.

This works as well.

Here is my Docker script which fails with the above error.

RUN su - bob -c ‘opam update -y’
RUN su - bob -c ‘opam install why3.1.3.3 alt-ergo.2.3.3 -y’

The two packages that fail have .tbz archives. I would suggest adding bzip2 to the packages you install, that should hopefully fix your problem.

This fixed my problem. Thank you.
