[Bug 816169] Re: When using Ensemble, add-apt-repository no longer functions properly

[Adam Gandelman]

Apologies! As it turns out, the failures I was seeing testing older
images was due to something unrelated in the hook executed by ensemble.
Eliminating that, the test succeeds on alpha1 cloud AMIs out-of-the-box.
However, alpha1 does not have python2.6 installed alongside 2.7 by
default.  Installing 2.6 and re-running add-apt-repository via ensemble
hook fails with a similar runpy.py error.

Unfortunately, I'm having trouble finding any way to reproduce this
manually without the use of ensemble.

Bug description:
  One of the changes made between Jul 22-25 caused add-apt-repository to
  quit working when being called from within an ensemble formula:

  + apt-add-repository ppa:cloudfoundry/ppa

  2011-07-25 22:55:32,383: hook.output at ERROR: Fatal Python error: Py_Initialize: Unable to get the locale encoding
    File "/usr/lib/python2.7/encodings/__init__.py", line 123
      raise CodecRegistryError,\
                              ^

  2011-07-25 22:55:32,384: hook.output at ERROR: SyntaxError: invalid
  syntax

  Ensemble does not set many env vars, so this may be the culprit.

  When running this from within an Ensemble script on an Oneiric
  install, the error above is yielded, and while the file in
  sources.list.d is written, it uses sid for the distro rather than
  oneiric.

  If manually logging in and subsequently running the command,
  everything works as it should, which leads me to believe it is an env
  var issue.
