I have recently installed Kubuntu 20.10 and since yesterday I am getting following error whenever I am trying to remove or install something from Discover.
You have no authorization to execute this operation
Below is the output when I tried to execute it from the Konsole.

I fixed it by running following command on Konsole.
Later on, I completely removed the chrome-remote-desktop package from Synaptics. I think, below command should also work if trying to remove from Konsole.
