I am happy to announce that we now have a PPA with gqrx and gnuradio packages for Ubuntu 12.04, 12.10, 13.04 and 13.10, so it should cover a wide range of Debian & derivative distributions.
Currently, the release channel is empty but it will be populated when Gqrx 2.2 is released in a few days.
All dependencies that are not available from the official repositories should be available through the PPA. The PPA is still a work in progress and we need people to test the packages. I have already tested with Funcube Dongle Pro, Pro+ and rtlsdr. Will also test with USRP and HackRF later.
Before using this PPA you must make sure that any prior installations of gnuradio and gqrx (manually or via script) are removed or disabled.
Once you have a GNU Radio-free computer, installing from this PPA is as simple as:
$ sudo apt-add-repository ppa:gqrx/snapshots
$ sudo apt-get install gqrx
For USB-based devices, you must copy the udev rules files to /etc/udev/rules.d/ manually. I will fix this later.
It has taken many days to get this up and running and I hope it will be useful. Feedback is welcome!
