Describe the bug I installed Solaar from Solaar git ppa (https://launchpad.net/~solaar-unifying/+archive/ubuntu/ppa), installation succeeded, but when I click on the Solaar icon to start the app, the app failed to start and resulted in error trace.

On my system, the udev files are located: /lib/udev/rules.d/60-solaar.rules /usr/share/solaar/udev-rules.d/42-logitech-unify-permissions.rules
