Hi all,
I upgrade the system to ubuntu 20.04 starting from iso.
Then I install GNURADIO 3.9.0.0 following the instruction in the wiki.
GNU radio is correctly installed because I'm able to run successfully top_block.py but I have problems building the flowgraf.
In attached picture of the error that I get : waveforms generator don't show frequency (even do in block editor is correctly assigned).
Of course I'm not able to generate any topblock.
I try to re-install gnuradio but get same error.
On internet I found some indication that the problem can be in grc.conf file global_block_patch but not working on my cases.
Thank you for help.
David
