As stated, I am doing the upgrade in two steps (0.21 -> 0.24 -> 0.27).

I think I figured out the issue.  I was keeping the hostname the same, 
so I did not pay much attention to the changing hostname issues.  
Indeed, I confirmed that the hostname was set to localhost in mythtv 
frontend setup.  What I did not realize (remember) is that there are two 
other places where the host IP address (not hostname) exists; in the 
mythtv backend setup (mythtv-setup) for the local BE and master BE.

So when I ran mythtv-setup (backend setup) after the first upgrade step, 
I also changed the local BE and master BE IP address to 127.0.0.1.  
mythtv frontend then completed it's upgrade with no issues.  This is a 
combined fronted/backend so that works.  When I am all done, I can then 
change these two IP address back to the real interface address, so other 
frontends (I currently have none) can access the BE.
