I just got to know EquationTrakker
because I need to do phase graphs for my classes.
When I load it
<< EquationTrekker`
everything works fine with no errors.
However when I try to use an example of the documentation, I get:
EquationTrekker[y''[x] + y[x] == 0, y, {x, π/8, 2 π}]

How can I fix this?
edit: forgot to mention I'm using Ubuntu 14.04. Haven't tried it on Windows 8 (dual boot)
edit2: It works properly on Windows 8. It looks like it's a problem with any java package in ubuntu...
