i provided the links to what i downloaded and installed.
i believe its just the latest official binary for your distro. windows, ubuntu/debian or macos.
of course i downloaded and installed ubuntu amd64 flavor
in my topic i listed sdrangel as 4.3.0
i do have alot of ppa's added for soapysdr, limesuite, gnuradio. etc...
i dont think there is a sdrangel ppa that i am aware of.
