Improve dependency install

[LeroyR]

Is your feature request related to a problem? Please describe. Most distributions require adding the ROS ppa to install dependencies. This is nowhere documented after running generate.

Example: When I call the generator like this: After calling

build-generator platform-requirements …

Most distributions(ROS) require adding of custom PPA which is documented nowhere

When I call the generator like this:

build-generator generate …

the output does not tell me that i may have to install dependencies

Describe the solution you'd like

• Add the possibility to define additional PPA+Keys that for a platform
• I would like it if the generator can prompt for the addition of PPAs defined within the distribution. Maybe after platform-requirements call?
• Add a generator-message variable to distributions where i can add custom messages after generate calls (default something along "Remember to run platform-requirements and install missing dependencies. "

Add the possibility to define additional PPA+Keys that for a platform

For the prototype docker stuff, I use the following:

platform-requires:
  ubuntu:
    packages:
      - …
    keys:
      - http://packages.osrfoundation.org/gazebo.key
    repositories:
      - deb http://packages.osrfoundation.org/gazebo/ubuntu-stable xenial main

Is that close to what you mean?

I would like it if the generator can prompt for the addition of PPAs defined within the distribution. Maybe after platform-requirements call?

What do you mean by "prompt"? And would the effect be?

Add a generator-message variable to distributions where i can add custom messages after generate calls (default something along "Remember to run platform-requirements and install missing dependencies. "

Good idea. Please make a separate issue for this.

Looks good.

Depends how easy it should be for the user:

1. Output of required PPA like deps now
2. Output install commands e.g. sudo sh -c 'echo "deb http://packages.ros.org/ros/ubuntu $(lsb_release -sc) main" > /etc/apt/sources.list.d/ros-latest.list'. , apt get install ....
3. "would you like to add/install ... now y/n" and automatic installation

Add a generator-message variable to distributions where i can add custom messages after generate calls (default something along "Remember to run platform-requirements and install missing dependencies. "

Good idea. Please make a separate issue for this.
