By utilizing the method put forth by and the policy files created by Allen Guarnes [https://www.allenguarnes.com/technology/resolving-the-missing-gksu-command-in-ubuntu-18-04/] you should be able to do what you want and have everything look just the same as it did. In ebery case I've tried, I've been able to replace gksu with pkexec. For example, the command gksu pcmanfm can be replaced with pkexec pcmanfm.<div dir="auto"><br></div><div dir="auto">Eric</div><div dir="auto">--</div><div dir="auto">Thank you,</div><div dir="auto">God bless you,</div><div dir="auto">Computers4Christians</div><div dir="auto">http://computers4christians.org</div></div></body></html>
