Check your ~/.gnuradio/config.conf file. In there is a section [modtool] and a "newmod_path=..."
Verify that matches the value of your installed path.
On mine it says:
[modtool]
newmod_path = /share/gnuradio/gr39/share/gnuradio/modtool/templates/gr-newmod
newmod_path = /share/gnuradio/gr39/share/gnuradio/modtool/templates/gr-newmod
For 3.9, there was a slight change in the behavior how GR finds the newmod path:
in that it will look wherever the currently installed prefix is, which can be seen with
gnuradio-config-info --prefix
Make sure your environment variables are sourced correctly - PATH, PYTHONPATH, LD_LIBRARY_PATH, and LIBRARY_PATH

Dear all,
on my Linux Mint (Ubuntu) box, I have installed and compiled GNU Radio
3.9 from source (master branch) as described here:
https://wiki.gnuradio.org/index.php/UbuntuInstall#Focal_Fossa_.2820.04.29
and here:
https://wiki.gnuradio.org/index.php/InstallingGR#From_Source
CMAKE_INSTALL_PREFIX is /usr.
GNU Radio compiles (without UHD and soapy support) and the tests are ok.
gnuradio-companion starts and everything seems ok. However, when I try
to create a new module with "gr_modtool newmod dl5eu", I get the error
message: ModToolException: Could not find gr-newmod source dir.
I have also tried what was necessary for Ubuntu 18:
$ cd /usr/share/gnuradio/modtool/templates/gr-newmod
$ sudo py3clean .
but this did not solve the problem.
With version 3.8 compiled from the maint-3.8 branch I don't have this
problem. Do you have an idea what I am doing wrong here?
Thank you very much.
Kind regards,
Ralf
