apt install gnuradio fails due to depends

tomdean; Hummmm ...

As we have " Depends: libgnuradio-atsc3.7.11 but it is not going to be installed", the question is why is it not install-able

The repo does have it; per:
apt list libgnuradio-atsc3.7.11

So as a poke at the situation to learn more - what results:
sudo apt install libgnuradio-atsc3.7.11

-the hunt is on-

Maybe a broken link in package dependencies???

Does gnuradio now install, or do we have to look at those other failed dependencies ?

-sometimes I do wonder-

Sorry, I was not clear. gnuradio did install, after I installed
libgslcblas0.

I tried sudo apt install libgnuradio-atsc3.7.11 - failed
Then, sudo apt install libgnuradio-fec3.7.11 - failed
Then, sudo apt install libgslcblas0 - success
Then, sudo apt install gnu radio - success

===============
There was one message when installing gnuradio:

Processing triggers for shared-mime-info (1.9-2) ...
/usr/share/mime/packages/gnuradio.xml:1: parser error : Start tag
expected, '<' not found
/usr/share/gnuradio/grc/freedesktop/gnuradio-grc.xml
^

Don't understand, yet, what the processing trigger message for
shared-mime-info means. So far, it has not caused a problem.

The XML error message is caused by a known bug, https://bugs.launchpad.net/ubuntu/+source/gnuradio/+bug/1769432
It should not do any harm.
There is a proposed workaround in the bug report:

rm /usr/share/mime/packages/gnuradio.xml
ln -s /usr/share/gnuradio/grc/freedesktop/gnuradio-grc.xml /usr/share/mime/packages/gnuradio.xml
