[Bug 1089389] Re: juju bootstrap fail behind a proxy when a gpg key must be imported

[Nate Mara]

I noticed that this problem can be fixed for me if the
GPG_DEFAULT_OPTIONS variable on line 171 of ppa.py is changed. If I add
these two properties to the list, then the problem goes away completely:

"--keyserver-options", "http-proxy=" + os.environ['http_proxy']

Obviously, you would want to check for the existence of this variable
before you just went using it, but it looks like this is the problem.
The PPA library does not forward the HTTP proxy settings along to GPG,
so GPG tries and fails to make a direct connection to the keyserver. Am
I missing something about the way this works, or can we make a similar
change and resolve these proxy issues?

Title:
  juju bootstrap fail behind a proxy when a gpg key must be imported

Status in software-properties package in Ubuntu:
  Triaged

Bug description:
  This is related to a Maas environment hosted behind a proxy.

  I'm trying to use 
  juju 0.6.0.1+bzr603-0juju1~precise1

  ubuntu at maas:~$ cat .juju/environments.yaml 
  environments:
    mymaas:
      type: maas
      maas-server: 'http://192.168.124.2:80/MAAS'
      maas-oauth: 'UP5Qay8Nsku8K98fqn:LjhnStY2HjfCeKfvmg:BxA586DWVNPKrT9ASNj9QasMvSPdgavt'
      admin-secret: 'nothing'
      default-series: precise
      juju-origin: ppa

  When juju boostrap, things do not behave as expected on the zookeeper
  node.

  Excerpt from the cloud-init-output.log:

  W: GPG error: http://ppa.launchpad.net precise Release: The following
  signatures couldn't be verified because the public key is not
  available: NO_PUBKEY 376A290EC8068B11

  On the zookeeper node, if i try to apt-add-repository , the needed gpg
  key is not injected, but the scrpit does not return any error code:

  ubuntu at zookeeper:/var/log$ sudo mv /etc/apt/sources.list.d/juju-pkgs-precise.list /tmp/
  ubuntu at zookeeper:/var/log$ sudo ls /etc/apt/sources.list.d/
  ubuntu at zookeeper:/var/log$ sudo apt-add-repository ppa:juju/pkgs --yes
  gpg: keyring `/tmp/tmpmlP7VA/secring.gpg' created
  gpg: keyring `/tmp/tmpmlP7VA/pubring.gpg' created
  gpg: requesting key C8068B11 from hkp server keyserver.ubuntu.com
  gpgkeys: key A2EB2DEC0BD7519B7B38BE38376A290EC8068B11 not found on keyserver
  gpg: no valid OpenPGP data found.
  gpg: Total number processed: 0
  recv failed
  ubuntu at zookeeper:/var/log$ echo $?
  0

  Trying to inject key while setting the http_proxy environment variable works better:
  ubuntu at zookeeper:/var/log$ sudo http_proxy=http://91.189.90.174:3128/ apt-add-repository ppa:juju/pkgs --yes
  gpg: keyring `/tmp/tmp1pAd6X/secring.gpg' created
  gpg: keyring `/tmp/tmp1pAd6X/pubring.gpg' created
  gpg: requesting key C8068B11 from hkp server keyserver.ubuntu.com
  gpg: /tmp/tmp1pAd6X/trustdb.gpg: trustdb created
  gpg: key C8068B11: public key "Launchpad Ensemble PPA" imported
  gpg: Total number processed: 1
  gpg:               imported: 1  (RSA: 1)
  OK
  ubuntu at zookeeper:/var/log$ echo $?
  0

  
  On the zookeeper node,  python-software-properties  is version   0.82.7.3
