$ sudo apt-get install gnuradio Reading package lists... Done Building dependency tree Reading state information... Done Package gnuradio is not available, but is referred to by another package.
This may mean that the package is missing, has been obsoleted, or is only available from another source
E: Package 'gnuradio' has no installation candidate
I have been searching the net to see if I could find any solutions. I found http://stackoverflow.com/questions/20041366/unable-to-locate-package-gnuradio-ubuntu-12-04 which might be same problem, although the poster doesn't show his output from . The suggested solution is to ettus repositories. This seems to be a case of symptom treatment when the installation guide indicates that gnuradio already should be in the standard repository.
