Ok, I'm back...

I've updated to ubuntu 15.04 which also solves the new python 2.7.9 dependency.

All other dependencies should be installed correctly (SIP 4.16.9, pyQT 5.4.1, QT 5.4.1)

When compiling calibre(2.38) I get the following error:

File "setup.py", line 13, in <module>
    import setup.commands as commands
  File "/home/odroid/Downloads/calibre-2.38.0/setup/commands.py", line 28, in <module>
    from setup.translations import POT, GetTranslations, Translations, ISO639, ISO3166

    process = Popen(stdout=PIPE, *popenargs, **kwargs)
  File "/usr/lib/python2.7/subprocess.py", line 710, in __init__
    errread, errwrite)
  File "/usr/lib/python2.7/subprocess.py", line 1335, in _execute_child
    raise child_exception
AttributeError: 'NoneType' object has no attribute 'rfind'

I've spend the last hours on google but couldn't find a solution.

Maybe someone here could help?

Btw: what was the last version of calibre with python 2.7.1?
