Could not set shared folder

  • 772

I'm running on Xubuntu 14.04.2 LTS. Trying to share a folder on a network via shares-admin and system-config-samba applications but they give me error.

command

sudo shares-admin

output:

error: XDG_RUNTIME_DIR not set in the environment.
error: XDG_RUNTIME_DIR not set in the environment.

(shares-admin:11220): Gtk-WARNING **: cannot open display:

command

sudo system-config-samba

output:

  1. Best Answer

    After some googling I ended up with this solution:

    pkexec env DISPLAY=$DISPLAY XAUTHORITY=$XAUTHORITY shares-admin

    It passes required environment variables to the new isolated environment. Since root doesn't have DISPLAY and XAUTHORITY variables in its environment, user must pass it before the root uses any application dependent on GUI.

    (Now I started to think how can I make them permanent when sudo called...)

  2. another solutions is to 

    sudo apt-get install gksu
gksu-properties

    Set authentication mode to sudo and grab mode to enable
