I met up with the same problem recently. I'm a newbie, so I don't know whether this can solve your problem, but here is my solution.
find out which desktop environment I'm using
ps -A | egrep -i "gnome|kde|mate|cinnamon|lx|xfce|jwm"search for the corresponding
policykitpackage and install it.sudo apt search policykit sudo apt install policykit-1-gnomemy desktop environment is GNOME
(I don't know whether this step is necessary)
exec /usr/lib/policykit-1-gnome/polkit-gnome-authentication-agent-1
and then my problem had gone.
