The `rc` here means - removed, config files are installed. To remove the config
files you need to run either `sudo apt-get remove --purge gnuradio` or `sudo
apt-get purge gnuradio`

You also have two versions of the various libgnuradio-* packages - 3.8.1 and
3.8.3. Although not strictly necessary my advice is it remove them all. After
removing libgnuradio-pmt all other should be removed automatically, but if not
list them explicitly
apt-get purge libgnuradio-pmt3.8.1 libgnuradio-pmt3.8.3

Strange! You need to put double quotes around the regex
find /usr -name "*gnuradio*"

At some point you've used sudo to install. To fix the ownership run
sudo chown --recursive mariom:mariom /home/mariom/prefix-3.8/

Don't use sudo when installing in your $HOME, it is not necessary.

Yes, you can just delete the whole directory.

It won't solve current problems but most probably would prevent problems in the

Does it work now and if not what error do you get? If you still get some errors
then first remove all libgnuradio packages, all leftovers, then do a clean
rebuild/reinstall, run your flowgraph and provide the full output.

You are welcome! It is more then normal to have a lot of questions and there is
nothing to be sorry about. Keep exploring and someday pay it forward by helping
other new users.
