Just two days ago I downloaded and installed Ubuntu 22.04, and noticed that gksu isn't available for it.
sudo apt-get install -y gksu

E: Package 'gksu' has no installation candidate
Not even snap has it.
snap install gksu
error: snap "gksu" not found
How to install and use gksu? Has it been replaced by some other program?
Update: I just found that gksu is deprecated, so it'd help to have some example commands that show how older gksu commands can be replaced with new ones. I'm sure this will help everyone who reaches this page searching for what happened to gksu.
