On a fresh Ubuntu 14.04 install I followed the tutorial from here: http://proyectosbeta.net/2015/05/tilestache-en-ubuntu-14-10-desktop/
When I reach the part http://localhost/tiles/tiles.py/osm/preview.html the link give me 500 error.
What can be the problem?

Did you try changing the repository to the latest version?
https://github.com/TileStache/TileStache
Also, is there anything in your Apache logs?
