docker-compose build failed

[pkix]

Hi there,

When running the command docker-compose build, it's failed with ERROR: Service 'ctobservatory' failed to build: The command '/bin/sh -c pip install -r /observatory/requirements.txt' returned a non-zero code: 1, does anyone who knows what's going on? thanks.

Encountering a similar/the same problem, here is the full output of docker-compose build:

Some packages could not be installed. This may mean that you have
requested an impossible situation or if you are using the unstable
distribution that some required packages have not yet been created
or been moved out of Incoming.
The following information may help to resolve the situation:

The following packages have unmet dependencies:
 libpq-dev : Depends: libssl-dev but it is not going to be installed
E: Unable to correct problems, you have held broken packages.
ERROR: Service 'ctobservatory' failed to build: The command '/bin/sh -c apt-get update &&     apt-get install -y apache2-dev libpq-dev libffi-dev gcc postgresql-client libpq-dev python3 python3-dev python3-pip wget --no-install-recommends' returned a non-zero code: 100

The problem seems to be somewhere with libpq-devs dependencies. When adding libssl-dev to Step 3 of observatory/Dockerfile one will encounter another error:

The following packages have unmet dependencies:
 libssl-dev : Depends: libssl1.0.0 (= 1.0.1t-1+deb8u6) but 1.0.2l-1~bpo8+1 is to be installed
E: Unable to correct problems, you have held broken packages.

A dirty fix for this would be downgrading to the specified version of libssl1.0.0, Step 3 of observatory/Dockerfile:

RUN apt-get update && \
    apt-get install -y --force-yes apache2-dev libffi-dev gcc postgresql-client libpq-dev libssl-dev libssl1.0.0=1.0.1t-1+deb8u6 python3 python3-dev python3-pip wget --no-install-recommends

This is definitely not a recommended way of fixing this and I am not even sure if this really fixes it (I am still encountering a few errors later in the build process) but at least it gets you half way through the building process.

Edit: This does lead to problems when running the observatory:

user@machine:~/git/ct-infrastructure$ docker logs ctinfrastructure_ctobservatory_1 
httpd: Syntax error on line 133 of /usr/local/apache2/conf/httpd.conf: Cannot load modules/mod_ssl.so into server: /usr/lib/x86_64-linux-gnu/libcrypto.so.1.0.0: version `OPENSSL_1.0.2' not found (required by /usr/local/apache2/modules/mod_ssl.so)

so this really should just be seen as a way to continue the build process, not as a way to make it useable.
