https://pgp.mit.edu/pks/lookup?op=get&search=0x1054B7A24BD6EC30 is the same key,
right? Why not copy the text from there and import it as-is, without doing
base64 decoding yourself? That's actually what we discussed here...

[mathias, 2014/11/27 00:30:18]

In fact I do not recall us discussing to use the stuff from that URL explicitly,
though I remember us discussing the possibility for something like that.
However, the link above is not the same key (it's for YUM and TAR.GZ, not DEB),
we'll use http://apt.puppetlabs.com/pubkey.gpg

+handle = subprocess.Popen(['apt-key', 'add', '-'], stdin=subprocess.PIPE)

[Wladimir Palant, 2014/11/17 16:43:36]

I was already considering asking for that handle to be closed when I realized
that this isn't actually a handle - it's a process object ;)

Maybe use a better variable name?

[mathias, 2014/11/27 00:30:18]

Done.

+decoded_key = base64.b64decode(PUPPETLABS_GPG_KEY)
+handle.communicate(decoded_key)
+
+with io.open('/etc/apt/sources.list.d/puppetlabs.list', 'wb') as handle:
+  handle.write(PUPPETLABS_SOURCES)
+
+with io.open('/etc/apt/preferences.d/puppetlabs', 'wb') as handle:
+  handle.write(PUPPETLABS_PREFS)

+subprocess.check_call(['apt-get', '-y', 'update'])
+subprocess.check_call(['apt-get', '-y', 'install', 'puppet'])

+
+if not os.path.exists('/etc/puppet/hiera.yaml'):
+  config = os.path.dirname(__file__) + '/hiera.yaml'

[Wladimir Palant, 2014/11/17 16:43:36]

Please use os.path.join() instead of string concatenation here.

[mathias, 2014/11/27 00:30:18]

Done.

+  if os.path.exists(config):
+    os.symlink(config, '/etc/puppet/hiera.yaml')
