sudo command fails in ubuntu 17.10 with keyError

Question

I upgraded to Ubuntu 17.10. Now when I run

sudo gedit

I get the error

Invalid MIT-MAGIC-COOKIE-1 keyError: Can't open display: :0

How to fix it?

Other root applications are broken on Wayland too (see bug 1713313 and bug 1713311 ). — N0rbert, Oct 22 '17 at 10:47

Run:

xhost local:user1

(Replace user1 with your username.)

sudo=root not user: xhost local:root. and this command may not work on waylnd which is default for 17.10 – ravery Oct 21 '17 at 08:43
in my case I use "xhost local:tom" and it works. – Oct 21 '17 at 09:24

then your .Xauthority has xhost local:root in it. you should correct your answer so that is applies to more users. – ravery Oct 21 '17 at 09:27
I think it is a poor quality answer as it throws out a command without explanation or information on how to reverse the command – Panther Oct 21 '17 at 13:19
xhost +local: does it – Feb 18 '18 at 21:05
