That's good advice in general.

But in this case, it seems the very-latest UHD doesn't quite "mesh"
properly with Gnu Radio, and if
you set the "wire format" in a UHD source/sink to "Automatic" you get
this error. Unfortunately,
"Automatic" is the default, but as a workaround, you can set the wire
format to "Complex int16".
