I'm rather new to ubuntu and linux in general, so bear with me. I'm trying to put abode flash on firefox manually, and to do so I think I need to copy and paste a few things into a certain folder that I need root access to. I'm running ubuntu 17.10.
I've tried:
sudo nautilus
which gives me
No protocol specified
Unable to init server: Could not connect: Connection refused
(nautilus:1130): Gtk-WARNING **: cannot open display: :0
and
gksudo nautilus
which gives me a popup message which says "unable to copy the user's Xauthorization file"
any help would be appreciated
