I’m working with mycroft on linux. I have yet to set up a speaker or microphone; so far I’ve just been using the client gui, so some of the errors make some sense. But somewhere in the setup the code encounters an error that isn’t handled by mcroft.
When I run ./start-mycroft.sh all, wait a little, and then ./stop-mycroft.sh, this is what I get in the voice log.

It then continues for about a 1300 more lines (all pasted in [pastebin.com/SnkMdZ7K](http://pastebin.com/SnkMdZ7K)) alternating between “During handling of the above exception, another exception occurred:” and web-pages-worth of html.
The only thing I’ve been able to find googling this error is that it happens when try to use an invalid url type or something, but I definitely don’t know where a url is being passed or why it’s wrong.
Somebody on a different stack overflow question said the person (who was not using mycroft) either had something wrong with their python, or their OS, and that their python probably had somehow been installed without https support.
Advice?

Hey,
It looks like your on an i686 based machine and we don’t have a Precise executable compiled for that architecture. So the script is receiving a 404 page instead which is the html you’re seeing in the log.
You should still be able to use PocketSphinx, but would need to build your own Precise package if you wanted to use that. This only affects the wake word functionality though, so if you’re just using the GUI / CLI then it shouldn’t affect your usage.
