Se eu subir na cadeia de dependências com um dos pacotes de erro, finalmente recebo:

The following information may help to resolve the situation:
The following packages have unmet dependencies:
libgnuradio-runtime : Depends: libvolk2.2 (>= 2.2.0) but it is not installable

E finalmente:
sudo apt-get install libvolk2.2

Reading state information... Done
Package libvolk2.2 is not available, but is referred to by another package.
This may mean that the package is missing, has been obsoleted, or
is only available from another source
E: Package 'libvolk2.2' has no installation candidate
Procurar libvolk2.2 indica que ele está no repositório sid (instável) do Debian. Porém quando procuro sobre a instalação do gnuradio, não encontro nada mencionado sobre a necessidade de usar repositórios sid. E também parece que se fosse esse o caso, o guia que usei mencionaria isso.
Portanto, antes de recorrer ao uso de repositórios sid e correr o risco de quebrar, gostaria de ver se há alguma outra coisa que não estou vendo e que seja necessária.
Obrigado por qualquer ajuda.
Ajuda seria muito apreciada.
[EDITAR] Gostaria de mencionar também que esta é uma nova instalação do 18.04, e AFAICT, o atualizador automático de software, tem tudo atualizado.

sudo add-apt-repository ppa:gnuradio/gnuradio-releases sudo add-apt-repository ppa:gnuradio/gnuradio-master sudo add-apt-repository ppa:gnuradio/gnuradio-releases-3.7
Você precisa adicionar apenas um dos repositórios PPA acima e não todos os três.

Sim, os pacotes ppa:gnuradio/gnuradio-masteratualmente parecem estar quebrados. Acabei de instalar com sucesso o gnuradio 3.8 do ppa:gnuradio/gnuradio-releasesrepositório.
Primeiro você precisa remover o ppa:gnuradio/gnuradio-releasese ppa:gnuradio/gnuradio-releases-3.7e depois tentar instalar novamentegnuradio
rm /etc/apt/sources.list.d/gnuradio-ubuntu-gnuradio-master-bionic.list
rm /etc/apt/sources.list.d/gnuradio-ubuntu-gnuradio-releases-3_7-bionic.list
apt-get install gnuradio
