The package is too old

[Vesa Solonen]

The package on Ubuntu 20.04 is too old to be usable with e.g. Airspy HF+ Discovery [1], that is the current flagship product of the Airspy team.

Version 1.4.2 available on 18.04 PPA [2] works fine with GQRX within the release (gqrx-sdr/focal, 2.12.1-1build2 amd64).

Manual install without uninstalling the system provided:

dpkg -i libairspyhf0_1.4.2-myriadrf1~bionic_amd64.deb
