Can't edit files in Lubuntu 13.10

[Kneekick]

Im trying to edit /etc/network/interface file and i was told to use

gksu gedit /etc/network/interface

But it didnt work, so I tried

gksu nautilus

didnt work, nothing happens. So I tried

sudo apt-get install gksu

but it was already installed. Anything i tried to do never made anything happen.
I tried adding myself to root group, and setting my main group to root.
I also tried to run

gksu PCManFM

And i have tried all with gksudo. I'm new with Linux so please help me out.

you need to use sudo to make you have root permissions to edit the interface file. So you need to use a certain editor like vi, vim, or whatever else. So you would type sudo vim /etc/network/interface.

it will ask you to type in a password then put you in the editor

Hi

There is a big learning curve with unix / Linux if you are a Windows user

I assume you have a graphics interface or desktop
When I started with Unix there was no desktop and we had to work from the command line
Then we got x-windows
Now there are a number of different interfaces
Case is vital. gedit is not Gedit in unix/ Linux

First try

gedit

Does it open a text editor window ?
If not this editor is not on path or is not installed

Next if it works gedit /path to file.../file name
gedit /etc/network/interface

Should open text editor with file you need to edit
But you won't have permission to save changes

Sudo seemed to work for you
Did it require you to enter a root password ?
Sudo or equivalent gives you root super user powers just for one command

Try sudo gedit /path to file/file name
See if this now try editing this file
sudo gedit /etc/network/interface

If you have a graphics desktop with a graphics file manager Which works & looks like Windows explorer you can navigate to folder & right click on interface and select edit

The trouble with trying to help you is there are so many versions on Linux and you can choose two or three different desktops

The default text editor in LUbuntu is Leafpad. Instead of installing yet another text editor, the easiest solution is to replace "gedit" with "leafpad" in your commands. So:

"sudo gedit /etc/network/interface" would become "sudo leafpad /etc/network/interface"

Have seen the **gksu** advised, but never understood why. It's only for then neckbeard VIM ? everything else gets sudo(ED) to grab root dibs?! I knew about the "ICEWEASEL" balony, but didn't know about name.changes for basic unix utilities. No GEDIT everywhere ?? Does it get crazy like "awk" --> "sqawk" ???

gedit is not a "basic Unix utility".
