Public bug reported:
Did a fresh Ubuntu studio 18.04 bionic install from
http://cdimage.ubuntu.com/ubuntustudio/dvd/current/HEADER.html
lsb_release -rd
Description: Ubuntu Bionic Beaver (development branch)
Release: 18.04
apt-cache policy gnuradio
gnuradio:
Installed: 3.7.11-6
Candidate: 3.7.11-6
Version table:
*** 3.7.11-6 500
500 http://nl.archive.ubuntu.com/ubuntu bionic/universe amd64 Packages
100 /var/lib/dpkg/status
Installed gqrx-sdr which has gnuradio as dependency.
sudo apt-get install update
sudo apt-get install upgrade
sudo apt-get install gqrx-sdr
sudo reboot
Now running flowgraphs with wx-gui or no-gui works fine.
Only when running QT-gui flowgraphs i get the following error:
