Not able to install libmysqlclient-dev or default-libmysqlclient-dev on 3.6.10-slim-stretch

[FlavioAlexander]

I am unable to install either default-libmysqlclient-dev or libmysqlclient-dev

Part of my DockerFile looks like

    apt-get install -y --no-install-recommends \
    curl \
    build-essential \
    ntp \
    python3-dev \
    python3-setuptools \
    mysql-client \
    postgresql-client && \ 
    default-libmysqlclient-dev \
    rm -rf /var/lib/apt/lists/*

Pat of the traceback is the following

update-alternatives: using /usr/share/postgresql/9.6/man/man1/psql.1.gz to provide /usr/share/man/man1/psql.1.gz (psql.1.gz) in auto mode

You've got your && mismatched there:

    mysql-client \
    postgresql-client && \ 
    default-libmysqlclient-dev \

Should be:

    mysql-client \
    postgresql-client \ 
    default-libmysqlclient-dev && \

In the future, these sorts of questions/requests would be more appropriately posted to the Docker Community Forums, the Docker Community Slack, or Stack Overflow.
