Hi @eirseb and welcome to the Joulescope forum!
We use the ubuntu-latest GitHub Actions runner to build the Joulescope UI for Ubuntu. GitHub updated this runner to Ubuntu 24.04 a while back. It appears that the Joulescope UI Ubuntu 24.04 builds do not run on 22.04.
Distributing binary GUI applications for Linux is a nightmare. I have been told that Flatpak can help somewhat. However, we have not investigated…
If you want to stay on Ubuntu 22.04, you can use the Python package to run from Python. See the README for instructions.
Does this help you get up and running?
