I've tired it a few times with various ubuntu flavors and am getting the same thing. I wonder if it's because when you install mysql-server, it jumps to an input screen and asks for a root password.

Same issue over here , Digitalocean droplet

The following packages have unmet dependencies: mysql-client : Depends: mysql-client-5.5 but it is not going to be installed mysql-server : Depends: mysql-server-5.5 but it is not going to be installed

SOLVED: Just: docker pull jbfink/docker-wordpress and he'll install all the dependencies https://index.docker.io/u/jbfink/docker-wordpress/

you can also use: https://index.docker.io/u/tutum/wordpress/

No, not solved... Pulling jbfink/docker-wordpress or building it manually makes no difference.

Also, I may be a docker newbie, but I am not even sure that makes sense.

Worked for me , I just pulled with the command and he installed all the dependencies alone .

Also, I may be a docker newbie, but I am not even sure that makes sense. I am quite confident the issue is that Ubuntu 14.04 (which I assume you run as well) is using mysql 5.6 and not 5.5, making the scripts fail. I also assume that since 14.04 is relative new they simply have not updated it yet.

EDIT: Yes I re-read and see the poster is indeed running 14.04 like me. Of course it fails trying to install mysql 5.5...

@haperlot jbfink/docker-wordpress is LAMP, not LEMP (meaning it uses Apache instead of Nginx). So that doesn't make sense.

Instead what needs to be done is someone needs to update the Dockerfile in this repo to fix the dependencies issue.

One way of doing that is comparing the Dockerfile proposed "solution" in this thread to the Dockerfile in this repo and updating it to see if the dependencies are fixed. Hopefully I'll have some time to look at the differences this afternoon.

@AsavarTzeth it's not a newbie thing. They are entirely different repos. The Docker containers created are different. While the one works (jbfind/docker-wordpress), it uses Apache as the HTTPD server instead of nginx, which is what this repo does. I'll see what I can do to offer a PR for this issue in the next day or so.

[AsavarTzeth]

What I don't get is why a meta-package like mysql-server and msql-client fails. Should it not simply get the latest version and be done with it? The build acts just as if it tried apt-get -y install mysql-server-5.5 but it should not.

Edit: Nvm I see the container is based on an earlier Ubuntu without access to 5.6. I realize this is not something I can comprehend at the moment. :)

I've forked the repo here and updated it to use trusty rather than precise. This resolves the dependencies issue but then creates a whole set of other ones as the default location for nginx in 14.04 is /usr/share/nginx/html rather than /usr/share/nginx/www. I've cleaned all of those up in the Dockerfile, start.sh and nginx-site.conf but I now just get an nginx 404 page for WP. Hopefully someone with a bit more nginx experience can work out why.

Hi Guys, sorry - I've been away due to some personal circumstances. I'll take a look into this once I get a chance. Happy to take a look at any PRs in the meantime though!

It worked fine on Ubuntu 12.x, looks like a 14.x issue.
