Ubuntu 14.04 gedit error cannot open display

Question

I'm trying to fix an apache2 error (see... Why is my Apache not working after upgrading to Ubuntu 14.04? to understand the error) but to do that I have to use gedit, now after installing gedit and using the command (shown in the link) sudo gedit /etc/apache2/sites-available/000-default.conf and I get this error... Gtk-WARNING **: cannot open display: Even if I try gksudo gedit /etc/apache2/sites-available/000-default.conf and sudo nano /etc/apache2/sites-available/000-default.conf it gives me the same message (including when I type in gksudo nano). What's the problem with this?

Solution

You do not have to use gedit. Since you are on a server system, likely with only a terminal console available, you will need to either use X11 forwarding with ssh, or a terminal based editor.

To edit the file under sudo, just use sudo nano rather than gksudo. If you wish to forward your display, you can use ssh -X and then gksudo and gedit will work, but be somewhat slow, depending on your connection to the server.

another problem is that with the "edit" command it says that I can't get access ot the file
