I have solved this bug myself. These were the steps: colin@colin:~$ find /usr/lib -name "lsb_release*" /usr/lib/python2.7/dist-packages/lsb_release.py /usr/lib/python2.7/dist-packages/lsb_release.pyc /usr/lib/python3/dist-packages/lsb_release.py /usr/lib/python3/dist-packages/__pycache__/lsb_release.cpython-32.pyc
colin@colin:~$ sudo rm /usr/lib/python3/dist- packages/__pycache__/lsb_release.cpython-32.pyc And to verify it worked: colin@colin:~$ python3 Python 3.2.3 (default, Oct 19 2012, 19:53:16) [GCC 4.7.2] on linux2 Type "help", "copyright", "credits" or "license" for more information. >>> import lsb_release >>> quit() colin@colin:~$ As you can see, no errors anymore on trying to import lsb_release. Running aptitude full-upgrade worked as well and finished configuring extlinux. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1093071 Title: can't import lsb_release in python3 anymore To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/lsb/+bug/1093071/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
