Traceback (most recent call last): File "/usr/lib/the-package/setup-package.py", line 3, in <module> from augeas import Augeas File "/usr/lib/python2.7/dist-packages/augeas.py", line 78, in <module> class Augeas(object): File "/usr/lib/python2.7/dist-packages/augeas.py", line 82, in Augeas _libaugeas = _dlopen("augeas") File "/usr/lib/python2.7/dist-packages/augeas.py", line 75, in _dlopen raise ImportError("Unable to import lib%s!" % args) ImportError: Unable to import libaugeas!
The _dlopen() function uses ctypes.util.find_library(), which is a fundamentally broken API. This is the culprit, not dpkg.
ldconfig is one of the triggers of libc-bin. It seems that its invocation is now postponed too late.
ldconfig is declared as a noawait trigger, so dpkg is allowed to configure the triggering package immediately, without waiting for the trigger to be run.
This declaration is correct, because running ldconfig shouldn't have any effect on software functionality, unless there's a bug somewhere else.
