How can I edit the fstab file?

Installing Zorin OS
1

OK, I'm totally new to linux in general, so I apologize for my questions, but I have been searching extensively to find answers. My problem is I'm installing Zorin and now I'd like to move my home directory to a second drive I have attached. I've gotten through all the steps, but now it says I have to add a line to my fstab file. I've tried gedit, mu I get errors. The command I'm trying is

sudo gedit /etc/fstab
to which I receive this -
mkdir: cannot create directory ‘/run/user/0’: Permission denied
Authorization required, but no authorization protocol specified

(gedit:16646): Gtk-WARNING **: 13:39:03.358: cannot open display: :0

I'm using Zorin 18. I have the thing working but it tells me if I don't edit this file it'll all come undone and it took my dumb *** a long time to do it so I don't want to mess it up. Please help.

Try

sudo nano /etc/fstab

instead. Graphical Interfaces like Gedit should not be opened in superuser like that.

Are you trying this through the Live environment?

You have to edit it through the installed system.

If you don't like editing /etc/fstab directly, you can also use the app disks to automount drives or partitions at boot.
