I don't know, it's been a couple of weeks since my last email from one of the developers. I'm not sure how this works but it seems that I can simply update the repositories myself although it seems a little rude to do so.

Somewhat related, I've noticed that ScanTool.net seems to connect to my Bluetooth OBD more reliably than Carman does. My guess is that this might be to do with it waiting for the ECU to timeout before trying to connect although it is a somewhat convoluted method of setting a timer and checking it in a loop to see when it has expired. A simple wait() statement would seem to suffice for this but unlike the mbed system, the N900/Linux/Maemo doesn't seem to have a wait() command! Instead I have seen sleep() (and variations of it) or select() proposed in different forums for the purpose. Can I simply use sleep() instead of wait() and how can I be sure that a 'signal' hasn't messed things up - the more I read about sleep() the more confused I become about what (and why) 'signals' and 'SIGALARM' are about or how they are anything but unhelpful

Adding '-f' to your install command might help, this tries to repair dependency errors:
I'm no expert in this either, more a lucky meddler, hopefully this will help.
