Installation of GNURadio v3.8 on Ubuntu 22.04 using PyBombs

Hi, 

I'm trying to install GNURadio v3.8 on Ubuntu 22.04(jammy) using PyBombs but I am getting an error. I would appreciate your help with this. 

Steps followed: 

sudo apt-get install python3-pip 

sudo pip3 install pybombs 

pybombs auto-config 

pybombs recipes add-defaults 

pybombs prefix init ~/prefix-3.8 -R gnuradio38.

Regards,

Kunal.
