Hmm. I have been assuming all this time that GNU Radio Companion is an optional GUI front end for GNU Radio, which must be installed separately. In my case, I definitely installed GNU Radio from source. However, when that was finished, I then went into Ubuntu Software and installed GNU Radio Companion, which placed an icon on my toolbar (which is how I launch the application). I am guessing this was the wrong thing to do? FYI -- If I open a terminal and type "gnuradio-companion", the GUI never launches, and all I get is the following error message: $ gnuradio-companion <<< Welcome to GNU Radio Companion 3.9.0.0 >>> Block paths: /usr/local/share/gnuradio/grc/blocks Loading: "/home/anyone/Documents/Brendan/GNU-Radio/save_rx_samples_to_file.grc" >>> Converting from XML /usr/lib/python3.6/importlib/_bootstrap.py:219: ImportWarning: can't resolve package from __spec__ or __package__, falling back on __name__ and __path__ return f(*args, **kwds) >>> Done Loading: "/home/anyone/Documents/Brendan/GNU-Radio/spectrum_analyser_two_chan.grc" >>> Converting from XML Segmentation fault (core dumped) To answer your other questions: If I type "/sbin/ldconfig -p | grep -F libuhd", here is what I get: libuhd.so.4.0.0 (libc6,x86-64) => /usr/local/lib/libuhd.so.4.0.0 libuhd.so.3.15.0 (libc6,x86-64) => /usr/lib/x86_64-linux-gnu/libuhd.so.3.15.0 libuhd.so.003.010.003 (libc6,x86-64) => /usr/lib/x86_64-linux-gnu/libuhd.so.003.010.003 libuhd.so (libc6,x86-64) => /usr/local/lib/libuhd.so Finally, when I type dpkg -S "(libuhd.so.003.010.003 "/usr/lib/x86_64-linux-gnu")", I get the response dpkg-query: no path found matching pattern *(libuhd.so.003.010.003 /usr/lib/x86_64-linux-gnu)* Regards, Brendan.
