Hi
I experienced a similar issue when using gr-osmosdr and
gr-limesdr too so my experience could help for this problem (I did
not use Adalm-Pluto)
I installed gnuradio 3.8.1 (bad idea since Synaptic always ask to
update to 3.8.2) OR 3.8.2 from
http://ppa.launchpad.net/gnuradio/gnuradio-releases/ubuntu; both
version led to the same issue
- The strange thing is that on my ubuntu 20.04 computer gnuradio
libraries (libgnuradio-xxxx.so) are under
/usr/lib/x86_64-linux-gnu, while gr-xxx package are generally
installed under /usr/local/lib/x86_64-linux-gnu.
- gr-osmosdr stuff was installed under
/usr/local/lib/x86_64-linux-gnu (a different folder fron
gnuradio libraries)
- futhermore, when for example 3.8.2 is installed from PPA, after adding gr-osmosdr from PPA, some 3.8.0 and 3.8.1 gnuradio libraries are installed beside 3.8.2 gnuradio libraries.
- I also found that removing 3.8.2 to install 3.8.1 (from ppa),
there remains 3.8.2 libraries
In my case I solved the issue by unsinstalling all gr-xxx package, (re)install GR 3.8.2, remove all remaining 3.8.1 or 3.8.0 libgnuradio libraries (if 3.8.2 is installed), and then compile and install all gr-xxx from source codes

Hello everyone,This is my first post in this list.I used gnuradio for some time yet, but recently I saved a acer Travelmate from Win7 and installed Ubuntu 20.04. I Installed gnuradio 3.8. I installed also gr-iio, libiio and libad9361-iio.
When I try to run a flowchart with plutosdr source, I have the message "ModuleNotFoundError: No module named 'iio'"I found several "solutions" on the net, but not one that worked for me.Anyone else had this problem and solved it?Thanks for your help!Freddy, ON7VQ
