Dpkg is again telling you what to do. "Unmet build dependencides", means you don't have the packages installed to build g15daemon. Install them using "apt-get install automake1.9 chrpath libg15render-dev libusb-dev libfreetype6-dev" or "apt-get build-dep g15daemon"
Also, I noticed that this bug is fixed in the last Ubuntu release. Maybe updating your Debian installation will help? -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/538259 Title: G-keys don't work on Logitech G15 keyboard To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/g15daemon/+bug/538259/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
