If your end goal is to install gr-baz, then you need to build it from
the source code.
It's old code and it assumes you have a UHD so you may need to install
UHD also to get it to build.
But to answer your question, you either need to build what you need from
source or upgrade ubuntu.
And then it may not be able to get gr-baz to work regardless of which
option you choose.

All,
I followed the install instructions from here:
https://wiki.gnuradio.org/index.php/InstallingGR
After uninstalling 3.7 that came from the Ubuntu repos, I did:
$ sudo add-apt-repository ppa:gnuradio/gnuradio-releases
$ sudo apt update
$ sudo apt install gnuradio
This gave me version 3.8.2.0 (Python 3.6.9) and not 3.9 as indicated.
I now have no source for my RTL dongle, nor do I have a "osmocom
source".
I note that during the install, one of the "Suggested Packages" is
gr-osmosdr however at the bottom of the website install instructions
it states "Attention: Do NOT try to install further packages like
`gr-osmosdr` via Ubuntu's package management (i.e. using "apt").
Ubuntu will try to install a potentially incompatible version and your
system will be in an undefined state."
How do I solve my RTL dongle and osmocom source problem?
Guidance appreciated.

Cinaed,
Thanks for the reply.
librtlsdr-dev was already installed. The other two were not and
pulled in some other dependencies during the install process.
This did not fix my problem though.
I couldn't install gr-baz from the ubuntu repo so followed the
build process for gr-baz on github. I could then get it to run, but
with no output.
After further reading, the website recommends a minimum version
of 3.8. I note that 3.9 is available via a PPA so will install that
and work through the tutorials (which I didn't find yesterday). Must
have had a "man" look ;-)
Thanks again for your assistance.

I'd recommend installing -the following - if you haven't already
done so
librtlsdr-dev
libosmosdr-dev
libosmocore-dev (not sure)
And I'm just guessing - I don't have gnuradio 3.7 or ubuntu installed.
Also,unless you were able to in install the ubuntu package gr-baz
from one of the ubuntu repositories - which is unlikely, then
download and built the code from
https://github.com/balint256/gr-baz
I's an OOT module which doesn't come with gnuradio.
And I would test using the rtl dongle with gnuradio. Create a
flowgraph with the "osmocom soure" and a "qt gui sink".

Good Evening,
I am taking my first tentative steps with GNU Radio.
I am using Ubuntu 18.04.6 LTS with a RTL2832U dongle from
RTL-SDR.COM. This combination works fine with CubicSDR and rtl_433.
I installed gnuradio-companion from the repo (sudo apt install
gnuradio) which gave me version 3.7.11-10.
I found a tutorial that built a FM receiver, so thought that
would be a good place to start.
After a few issues building the receiver (solved with google),
I finally got to the point where I could execute the flow graph.
Now I get the following in the terminal:
Executing: /usr/bin/python -u
/data/Amateur_Radio/SDR/GNU-radio/top_block.py
Traceback (most recent call last):
File "/data/Amateur_Radio/SDR/GNU-radio/top_block.py", line 35,
in <module>
import baz
File "/usr/local/lib/python2.7/dist-packages/baz/__init__.py",
line 40, in <module>
from baz_swig import *
ImportError: No module named baz_swig
I can see there is "No module named baz_swig" but no amount of
googling yielded a solution.
Hoping someone can help.
Regards,
Ian
