Thank you for taking the time to report this bug and trying to help make Ubuntu better. It looks like you may have a locally built version of Octave installed besides the version installed from the official Ubuntu repositories. The version of Octave provided by Ubuntu does not use the libqscintilla2 library. Can you check the directories in your PATH for other copies of Octave?
1. What does "which octave" in a terminal show? 2. Is there a copy of Octave at /usr/local/bin/octave ? If there is an octave outside of /usr/bin/octave installed by the Ubuntu package, please remove it and try installing again. Let us know if you are able to install successfully after removing or moving other copies of Octave out of the way. ** Changed in: octave (Ubuntu) Status: New => Incomplete -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1280920 Title: octave dependency error on libscintilla2 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/octave/+bug/1280920/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
