When I am trying to restart/shutdown my Ubuntu 18.04, it requires authentication, showing dialog box with message:
"Authentication is required for rebooting/powering_off the system while an application asked to inhibit it"
Is there any way to clear off application inhibition?
History: I was trying to install droidcam in ubuntu 18.04, but it turned out no device driver was installed "/dev/video[0-9]", according to solution I tried "sudo apt-get install linux-generic" and I killed the process in between,in the terminal. I don't know exactly how to get off this, can anyone help me?
