Tom, This was an unfortunate consequence of updating the main gnuradio-releases PPA to 3.9 (since it is the latest release). Clearly we need a strategy here and to learn how PPAs are handled on other projects.
There is currently a gnuradio-releases-3.8 repository, so if you are planning to stay with 3.8 (currently 3.8.2.0) and the supported 3.8 OOTs, this would be the PPA to switch over to. see: https://wiki.gnuradio.org/index.php/InstallingGR#Ubuntu_PPA_Installation I apologize for the lack of communication in this shift. One of our goals going forward is to make installation of GNU Radio easier and more straightforward, and the Ubuntu PPA has been one of our main installation channels. Ideally .deb packages will be built as part of the CI in the future as well to keep master builds up to date as well. If anyone has insight or experience with doing this in an automated way, please reach out. Nick - thank you for the recommendation to create the version specific metapackage. Would this be preferable to a separate PPA? The separate PPA was done out of convenience more than anything. In the main Ubuntu repository, only the pre 3.8 release candidate made it there in time, so without a PPA specified, that what gets installed from apt-get.
