"Command 'gksu' not found" error on Ubuntu 18.04 [duplicate]

While running

gksu gedit /etc/udev/rules.d/somefile.rules

I am getting this suggestion.

Command 'gksu' not found, did you mean: command 'gosu' from deb gosu command 'ksu' from deb heimdal-clients command 'ksu' from deb krb5-user
Try: sudo apt install <deb name>

gksu has been deprecated.

It's been removed from Ubuntu 18.04, as well as Debian and other newer Linux distributions. If you do a web search with the phrase "Ubuntu man gksu", you will see there's no 18.04 version available. Here are alternatives:

Alternate[0]: use "-H"

sudo -H nautilus

Alternate[1]: Use "admin://"

gedit admin:///etc/udev/rules.d/somefile.rules

Alternate[2]: Use "pkexec"

pkexec gedit
