RouteConverter On Chromebook within Crouton

[routeconverter]

[*]I started with brouter using car-test but I only get a straight line. Does it need to download stuff from brouter or is it using the api (or whatever) to http://brouter.de/brouter-web/ ? 

Both Routers needs to download routing information from external servers. You should see it in Extras/Downloads...

[*]Then I tried to calculate a route with graphhopper. it needs to download the relevant pbf. No problem as such but I get a CRC error when downloading maps.

Most of the time this means that the data on the external server has been updated and you're the first to download it. And the catalog of external data is updated after this download but as the first downloader you see the error message. It's irritating and I'm thinking about ways how to fix it.

[*]Then I tried beeline, but that seems not to do anything as I get a straight line as well. (or is that what it is: beeline -> a bee flying in a straight line?)

You're right. It's a straight line connecting the positions - like for a track.

[*]Beeline was the last option I tried but now I can't select graphhopper or brouter anymore. Neither after restarting.

Strange. Are you using the latest prerelease?
