Hi @joulescopeluver and welcome to the Joulescope forum! As of Jul 2025, the offiicial Joulescope UI distribution only supports Linux for Ubuntu 24.04 LTS.
You should be able to run the UI as a Python package on other Linux distributions. See the README. You will want to use a virtual Python environment on Ubuntu.
Also see Joulescope UI fails to launch on Ubuntu 22.04 - #2 by mliberty.
Does this work for you?
