This command fixed it for me. It reinstall the python 2 and 3 decorator package.
apt install --reinstall python\*-decorator # Explanation: On Debian place or python3 packages (/usr/lib/python3/dist-packages/) the scipy/_lib/decorator module is a symlink to the decorator module it self. /usr/lib/python3/dist-packages/scipy/_lib# ls -l decorator.py lrwxrwxrwx 1 root root 18 Sep 25 06:25 decorator.py -> ../../decorator.py The package python-decorator and python3-decorator is a requirement for python-scipy and python3-scipy. According to apt, these decorator packages are installed. I checked the installed files with: # dpkg -L python3-decorator /. /usr /usr/lib /usr/lib/python3 /usr/lib/python3/dist-packages /usr/lib/python3/dist-packages/decorator.py /usr/lib/python3/dist-packages/decorator-4.0.6.egg-info (...) But the file /usr/lib/python3/dist-packages/decorator.py was missing. Something in my system should (the user perhaps) should have messed with it. After I forced the reinstall of this packages, it came back to work again. But it's really strange this file gone missing. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1621803 Title: package python3-scipy 0.17.0-1 failed to install/upgrade: subprocess installed post-installation script returned error exit status 1 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/python-scipy/+bug/1621803/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
