Comment 2 for bug 1638373

Something is really odd about Inkscape on Ubuntu 16.10. In the answers section, there was someone who didn't have all the filters available anymore after an upgrade...

@Jakub: Can you compare your file at /usr/share/inkscape/markers/markers.svg with this file (sorry for long link):

That's the one that *should* be in that location.
