[SOLVED] How to edit text files as Super User

[jpc2769]

Before I upgraded to 18.04, if i needed to edit e.g. a config file as a superuser, I would type

sudo kate <file name>

Now when I type that it says this:

:~$ sudo kate /etc/resolvconf/resolv.conf.d/base
Executing Kate as root is not possible. To edit files as root use:
SUDO_EDITOR=kate sudoedit <file>
:~$ SUDO-EDITOR=kate sudoedit /etc/resolvconf/resolv.conf.d/base
SUDO-EDITOR=kate: command not found

I also tried "sudoedit: /etc/resolvconf/resolv.conf.d/base", I get an old school text editor with nothing at all showing in the file, just like a blank .txt file.

Open your file in Kate. Edit it. When you go to save it, you'll be prompted for your password if it's a file that needs elevated privileges.

No need for sudo, gksudo, kdesudo, pkexec, etc.

Follow chimak111's post. But to answer the question as to why what you typed didn't work, you used a hyphen instead of an underscore in the error instructions.

Executing Kate as root is not possible. To edit files as root use:
SUDO_EDITOR=kate sudoedit <file>

Note the red underscore in the command above.
