I can reproduce the bug on my machine, it looks like some part of path is missing. When comparing to the initial path of an old installation (2.9.15) it looks like these 4 are missing now: /usr/local/share/octave/site-m /usr/share/octave/site/m /usr/share/octave/site/m/startup /usr/lib/octave/3.0.1/oct/i486-pc-linux-gnu
