Sorry for the delay in responding.  Just wanted to check in and note that the osmocom OP25 repo now has a patch for building OP25 with python3/gnuradio3.8.  Additionally, the principal python apps (rx.py, multi_rx.py et al). have been rewritten to run under either python 2 or 3.

So far after clearing away several nitpicks related to python3 everything appears to be solid.

Also it should be noted that the 'max' branch of the osmocom OP25 repo has been deprecated and is slated to be deleted at some point.  Going forward all new commits will be made directly to the 'master' branch - this also includes the gr3.8 patch.

Please report any problems esp. with but not limited to these modifications...

To provide a little bit of hope:  

I recently when through updating TwoToneDetect from Python 2.7 to 3.X.  I had been putting it off for a long time and was dreading it, but in the end it didn't end up being as bad as I had feared.  I used 2to3 as a starting point and that took care of easy stuff like print statements, and then after that just started tackling the error messages one at a time...after a few of those...all of a sudden it worked.  What I had anticipated taking weeks ended up only taking a few hours.  OP25 is certainly more complex and will likely take more effort, but hopefully it'll be a similar experience.

Thats what I figured... and thats why my own Python stuff is not 
compatible with 3.x...I'd really like to find these people who feel 
the need to change stuff that breaks things and flog them.

I am none to happy with things moving in this direction be GNUR or 
just in general.. I'd honestly like to see python3 rm -r *'d from the 
planet and just improve 2.x WITHOUT BREAKING THE ABI! Buttttt nooooo! 
We can't be that sensible.

Not exactly sure what my plan is on my little programs as they are 
mission critical for me/work..Move to some 18.04 VM's/LXC's and 
possibly sit tight there.. I am not a fan of change. :) :) ;)

There is a 2to3 script thing I will run that on things to see where it 
flags stuff, it might at least be a good reference point to start 
from...

I am working on an updated install.sh for 18.10-19.10 where cmake 
fubars up things...and it will flag 20.04 as incompatible and stop 
till advised. I'll get that to as soon as I work it all out to my 
sanctification.
