Harald,
Did you use the Python3 instructions? Did you do the
"Note: If you are building UHD-3.14 or previous, run the following
commands:
sudo apt install python
sudo apt install python-pip
sudo pip install mako requests numpy
"?
Also, if you are starting over, you need to delete the folder "~/gr38"
(or whatever you used) and start fresh. It gets confused if you try to
re-use the same folder. Also, I suspect that to have both versions in
your computer, *both* will need to be built with PyBOMBS rather than
having one in the system files.
Keep us posted. 73,

Hello Barry, all,
many thanks for the answer.
I followed your recommendation with the source build link (swap file
and some extra install).
Second i stepped in the pybombs build.
I decided to start with build of ~/gr38.
It stops here: (i assumed that it would be better to keep the runing
binary)
--snip---
Install uhd from source despite binary install available Y/[N]? n
[ERROR] Error installing package uhd. Aborting.
--end--
Second run was with Y, unfortunately with this result:
--snip--

... much more
--end--
BTW: ~/gr38 is almost empty, only src/uhd (i fear many of the build is
installed in a place where it interferes with the existing
installation?)
I am lacking knowledge to proceed, sorry.
Regards and vy73

Hi Harald,
One possibility is to use PyBOMBS to build two separate folders which
are independent of the system files so there is no confusion.
See https://github.com/gnuradio/pybombs#pybombs You could build 3.7
in a folder named ~/GR37 and 3.8 in a folder ~/GR38 and each folder
would have all of the libraries contained within those folders. It
would take a while to build, but should work OK once you are done.
To speed up compile time you might set up a swap file. See
https://wiki.gnuradio.org/index.php/InstallingGRFromSource_on_Raspberry_Pi
for reference.
I worked on the documentation of both, so please let me know if you
run into any problems.
Happy holidays and 73,
