Re: apt-get breaks gnuradio

I think Paul is right - we stepped the PPA version up with the correct numbering scheme, but that seems to conflict with the dependencies of OOTs.  There are a couple of ways to deal with OOTs in the future, but we don't have an immediate solution other than don't mix the PPA with the packaged OOTs. 

I'm going to try some things today and see if it helps.  I can reproduce the error in a docker by
add-apt-repository ppa:gnuradio/gnuradio-releases
apt-get update
apt install gnuradio
apt install gr-osmosdr
apt --fix-broken install

Hi Bradley,

Unfortunately, the PPA repository is in a bit of a broken state at the
moment: You can install GNU Radio itself from the repository, and it
works fine, but anything like gr-osmosdr which is not in the repository
will be dependent on the libraries as shipped with the Ubuntu release.

At the moment, you can't combine those. So if you need those, you might
have to forego the repository.

There has been some discussion on how to properly fix this, either in
the repository, or by getting Ubuntu 20.04 to ship a more recent build
of GR.

What you should be able to do is remove everything gnu radio related in
one go, as then there is no dependency issue any more. That's how I
resolved it a few days back.

Regards, Paul Boven.
