I tried and failed to install gnuradio-dev a week ago, and gave up. Little did I know, apparently my botched attemps has put APT into a real bind. Installing, removing, or running dist-upgrade (or any other APT command) leaves me with dependency errors.

I opened Software Center to see if there were suggestions where, and it offered to repair. That failed, but I did finally get a useful error message:

I don't need gnuradio on here - I am happy removing it, but I get the dependency errors when I apt-get remove. I worked through the first part of How do I resolve unmet dependencies after adding a PPA? (up to the PPA part) but no dice.

Other ideas? Even nuclear? Perfectly willing to just nuke all the gnuradio stuff and get a working machine back.

    Did you try removing gr-osmosdr too? sudo apt-get remove libgnuradio-iqbalance gr-osmosdr. – roadmr Jun 09 '15 at 20:23
  • Holy crap. I ... I didn't know you could do that. Worked perfectly. Put in a regular answer so I can gift you with imaginary Internet points. – Bill Sempf Jun 09 '15 at 21:27
  • I was able to resolve this same problem (but on 16.04) by following the instructions at: http://gqrx.dk/download/install-ubuntu specifically, I think the apt-get purge commands are what fixes the problem. Then reinstalling gnuradio and gqrx seems to go smoothly. I haven't had an issue with the packaging system and upgrades since. –  Sep 13 '16 at 22:46
