Add FPComplete repositories to enable stack/Haskell builds

[brendanhay]

This is to allow installation of stack tooling via apt addons - which can then be used to build Haskell jobs in the new container-based infrastructure.

This PR now contains all of the Ubuntu versions available in the fpco repo. See travis-ci/travis-ci#4169.

I found this issue from the stack user guide. What is the current status? Is it abandoned?

Can we merge this?

In #72, people list https://s3.amazonaws.com/download.fpcomplete.com/ubuntu/fpco.key as download URL. If that's indeed supported (please @snoyberg confirm), that might be better just because it's HTTPS. But moving on to the bigger problem...

[borsboom]

https://s3.amazonaws.com/download.fpcomplete.com/ubuntu/fpco.key is indeed supported, and recommended.

It would also be good to switch the repos over to the new, more conformant, paths:

• deb http://download.fpcomplete.com/ubuntu wily main
• deb http://download.fpcomplete.com/ubuntu vivid main
• deb http://download.fpcomplete.com/ubuntu utopic main
• deb http://download.fpcomplete.com/ubuntu trusty main
• deb http://download.fpcomplete.com/ubuntu precise main

Beyond these concerns (which are easy to address): What's the holdout? /cc @BanzaiMan
I know (from past issues) that Travis lacks internal expertise on Haskell. How can we help with that?

Would it help to point out Stack is a major build tool for Haskell and sorely needed on Travis, and it's listed on https://www.haskell.org/downloads?

Or do you need some review of the tool? Stack doesn't install setuid binaries or anything, so that shouldn't be a problem.

Ping @brendanhay - the stuff mentioned by @borsboom seems to be a low-hanging fruit.

Otherwise, any issues remaining from the Travis side? @BanzaiMan?

Stack is pretty important to the haskell community, its quite silly that this has been outstanding for over a year now. I went and looked at other PRs and saw some of them accepted within a day, whats the hold-up here?

[Blaisorblade]

Usual core problem: Travis has no Haskell people. But still.

👍 anything we Haskellers can do to get this done?

[jhance]

I think if someone could take over the PR and change the URLs to those that are suggested in the comments section here, that might help drive it (both the key and the conformant urls)

I can do so myself after work if nobody does it by then...

[BanzaiMan]

Sorry for the delay. If you need additional APT sources, please use GCE with sudo: required. Thanks.

[jhance]

Why are you unable to allow Haskell users to use the container-based infrastructure?

@Blaisorblade Thanks for the info. I'm closing this as a duplicate, then. We will continue discussion on #295.

@mgsloan @snoyberg does this mean that https://docs.haskellstack.org/en/stable/travis_ci/ can be updated now?

Edit: ah sorry nvm: travis-ci/apt-package-safelist#379 is still pending I guess...
