"Command 'gksu' not found" error on Ubuntu 18.04

Question

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

Don't think just `pkexec gedit` would work without any system modification first. You'll most likely get 'connection refused' error. – pomsky Nov 28 '19 at 07:35
Thanks for the comment and edit. @pomsky – Sakthivel A R Nov 28 '19 at 08:22

If only for gedit, I personally prefer `VISUAL=gedit sudoedit /etc/fstab` – Alvin Liang Nov 28 '19 at 09:23
What is the difference between alternatives? – Kevin Patel Mar 11 '22 at 22:14
