mysql-server installation doesn't work anymore

[Franselbaer]

I will try to get a solution around this.

Step 8 : RUN apt-get -y install puppetmaster-passenger puppet-dashboard puppetdb puppetdb-terminus redis-server supervisor openssh-server net-tools mysql-server

The following packages have unmet dependencies:
 mysql-server : Depends: mysql-server-5.5 but it is not going to be installed
 puppet-dashboard : Depends: mysql-client
                    Recommends: libapache2-mod-passenger but it is not going to be installed
 puppetdb : Depends: java7-runtime-headless or
                     j2re1.7 but it is not installable
 puppetmaster-passenger : Depends: apache2
                          Depends: libapache2-mod-passenger but it is not going to be installed
 supervisor : Depends: python (>= 2.3) but it is not going to be installed
              Depends: python-medusa (>= 0.5.4) but it is not going to be installed
              Depends: python-meld3 but it is not going to be installed
              Depends: python-pkg-resources (>= 0.6c7) but it is not going to be installed
              Depends: python-support (>= 0.90.0) but it is not going to be installed

If you change:

RUN echo "deb http://archive.ubuntu.com/ubuntu precise main universe multiverse" > /etc/apt/sources.list

to:

RUN echo "deb http://archive.ubuntu.com/ubuntu precise main universe multiverse" >> /etc/apt/sources.list

it'll work again. I'll try to get a better way because apt is complaining duplicate entries.
