Hello dear usrp users,
After a succesfull uhd_usrp_probe when trying to run the Ettus E320 on
Gnu Radio I get the following error message:

I updated GNU Radio from 3.8 to 3.10. The versions on the device are:
gnuradio-config-info -v
3.10.7.0

uhd_config_info --version
UHD 4.7.0.0-0-ga5ed1872

While GNU Radio is running, it detects the UHD version as
|UHD_3.15.0.0-release|. What could be the reason for this, and how can
I resolve it?

This is because you have a "mixed version" system on your Ubuntu
system. How did you upgrade Gnu Radio from
the version packaged by Ubuntu 20.04?
It's likely that what happened was that you did a source build of Gnu
Radio, and it found the packaged UHD library
on your system (3.15), and used that.
