Hey folks, the package I posted prevents system upgrades. Please install the original 1.0-25 from the same place if you installed my version:

I'm REALLY sorry about that.

If anyone wants the details: osso-software-version depends on osso-gpsd 1.0-25. I did not think about this, and made my version 1.0-25-jku0 (this is normally good practice as otherwise you can't tell which version you have). This is not a problem while installing, but apt starts to complain when you try to upgrade.

Again, sorry for the trouble. I'll post a new thread to make sure everyone notices.
