I always build from source as there are some additions from dl2stg
needed for HiQSDR support.
I think I'll ask him to submit them upstream.

for me that usually means I forgot sudo ldconfig Best, Bastian
That's not it.
When I initially installed it, gnuradio-companion worked on openSUSE
x86_64 and Ubuntu ARM for some days, so my guess was that something in
subsequent updates caused the problem.
That's why I rebuilt the ARM version but got exactly the same problem.

If you initially installed from binary, and then installed from
source, the PYTHONPATH locations are different.
A typical source install installs to /usr/local whereas a packaged
install installs to /usr
