I have an ext HDD attached to my nas, mounting errors.
 

"An error occurred while mounting /media/public."
IBUS-WARNING**:The owner of /home/hazel/.config/ibus/bus is not root!
Now I'm left with the file "public" which says "only system administrators have the permission to do this." Can I get out of this and mount it properly?

Sincerely,
Hazel

Maybe try sudo on mount command?

We may need to know a bit more about the setup too.

I think I need you to be more specific. I'm not sure I understood you, but I think I tried remounting "public" with no success because there were errors.

Your error states this. "only system administrators have the permission to do this." when you attempt to mount a resource.

From other web pages I assume that you could mount this resource as a user that has elevated permissions. Generally a command line thing.

sudo is a way to allow common users an ability to run elevated commands.
It is generally preferred over logging into su or (switch user) to (usually) root. Your admin user could be named almost anything.

So, what were the errors when you tried to use an admin user?
