hi guys this error just happened to me when trying to import basestring from setuptools.compat (that also uses ctype). just note that it just happened today after upgrading ubuntu 14.10 to 15.04 (this code was working before)
i got the following exception: File "/home/danfromisrael/Dev/Projects/TodoApp/Server/Domain/Core/Jsonable.py", line 4, in <module> from setuptools.compat import basestring File "/home/danfromisrael/TodoAppEnv/lib/python3.4/site-packages/setuptools/__init__.py", line 11, in <module> from setuptools.extension import Extension File "/home/danfromisrael/TodoAppEnv/lib/python3.4/site-packages/setuptools/extension.py", line 8, in <module> from .dist import _get_unpatched File "/home/danfromisrael/TodoAppEnv/lib/python3.4/site-packages/setuptools/dist.py", line 18, in <module> from setuptools import windows_support File "/home/danfromisrael/TodoAppEnv/lib/python3.4/site-packages/setuptools/windows_support.py", line 2, in <module> import ctypes File "/usr/lib/python3.4/ctypes/__init__.py", line 7, in <module> from _ctypes import Union, Structure, Array ImportError: /usr/lib/python3.4/lib-dynload/_ctypes.cpython-34m-x86_64-linux-gnu.so: undefined symbol: _PyTraceback_Add hope it helps Dan -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to click-apparmor in Ubuntu. https://bugs.launchpad.net/bugs/1444347 Title: /usr/bin/aa-clickhook:ImportError:/usr/bin/aa- clickhook@14:/usr/lib/python3/dist- packages/apparmor/click.py@15:/usr/lib/python3.4/ctypes/__init__.py@7 Status in the base for Ubuntu mobile products: New Status in Ubuntu system image (server/client/updater): Triaged Status in click-apparmor package in Ubuntu: Invalid Status in python3.4 package in Ubuntu: Invalid Bug description: The Ubuntu Error Tracker has been receiving reports about a problem regarding click-apparmor.
