Hi Nick, I'd personally say that the GNU Radio packages in Ubuntu should be pretty up to date (thanks, Maitland!), but the UHD in Ubuntu is extremely old, so if you want to use USRPs, you can't use Ubuntu's GNU Radio. Since building isn't that hard nowadays, and you had bad experiences with the Ubuntu package, I'd just try using pybombs [1]:
git clone --recursive https://github.com/pybombs/pybombs.git && cd pybombs && ./pybombs install gnuradio You should be able to answer all questions with the default (just <enter> your way through the dialog), then after everything is complete: ./pybombs env and add the generated file to your bashrc: echo "source <path that was used as prefix>/setup_env.sh" >> ~/.bashrc Open up a new terminal and run gnuradio-companion.
