Thank you for taking the time to report this bug and helping to make Ubuntu better. This octave upgrade error appears to be due to a missing shared library that should be present on your system based on the list of packages that were upgraded at the same time. This may be due to local configuration changes, packages installed from PPAs, or the nvidia driver packages.
Please paste the output of the following commands: update-alternatives --display x86_64-linux-gnu_gl_conf ls -l /usr/lib/x86_64-linux-gnu/mesa ldconfig -p | grep libGL ** Changed in: octave (Ubuntu) Status: Confirmed => Incomplete -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1311220 Title: apport crashes on system startup after upgrading from Saucy to Trusty To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/octave/+bug/1311220/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
