21 + locale.setlocale(locale.LC_ALL, '')

Why are you setting this?

+ if return_code not in (0,256): #256 = user rejected installation
29 + print >> sys.stderr, _("A problem occured during installation. apt-get returned %d") % return_code

I would just do if return_code != 0, I don't know if there is any value as the failing installation probably leaves enough information to the user anyway.
