I have Ubuntu 20.04 installed on my computer, and recently I've abandoned Gnome in favor of AwesomeWM. I've since learned that a DE is much more fleshed-out than just using a WM, so I've had to rice and patch the WM along the way, such as various widgets, etc.

My latest discovery is using Balena Etcher to flash an ISO onto a USB stick. I get an error that No polkit authentication agent found. Assuming that the policykit authentication agent simply wasn't autostarting in AwesomeWM (for whatever reason), I found my policykit via sudo apt list | grep policykit, put that in my rc.lua as awful.spawn.with_shell("policykit-1-gnome"), and restarted Awesome.

That didn't do anything, I'm still receiving the error. So what is causing that authentication failure?

  • Firstly you should confirm your polkit.service is running or not.
