I just have updated pip as found in a forum: wget https://pypi.python.org/packages/32/67/572f642e6e42c580d3154964cfbab7d9322c23b0f417c6c01fdd206a2777/pip-10.0.0b2.tar.gz#md5=cbfc1208d00bb72aba19431a7bb4afd5 tar -xzvf pip-10.0.0b2.tar.gz cd pip-10.0.0b2/ sudo python3 setup.py install
But I still couldn't install the debian module. Then I did that (I think I did that before): sudo apt-get --reinstall install python-debian After a reboot there was no crash anymore. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1756544 Title: package update-notifier-common 3.168.8 failed to install/upgrade: Unterprozess installiertes post-installation-Skript gab den Fehlerwert 1 zurück To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/update-notifier/+bug/1756544/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
