image builder: does not import PPA signing key

[Evan]

As discussed in https://code.launchpad.net/~pwlars/ubuntu-ci-services-itself/use-the-force/+merge/210505, we do not import the PPA signing key, which will break apt-get install during the image build.

I was looking at ev's branch - is there any reason we don't just call "apt-add-repository ppa:user/repository" instead of all the code he's doing?

Where is that branch ?

> apt-add-repository ppa:user/repository

As demonstrated by your hack yesterday, *this* works. The only caveat I can think of is that it requires some package to be installed but I more or less think it's part of the standard cloud image at least starting with saucy so we should be fine (worth checking though).

Given http://bazaar.launchpad.net/~canonical-ci-engineering/ubuntu-ci-services-itself/trunk/revision/373, should we move this to backlog?

[Andy Doan (doanac)]

I say we keep this open for now while I add the ability to do this for private ppas.
