Android : Android can not connect to Ubuntu 14.04

I tried many way like

-installing MTP tools on my Ubuntu 14.04

-Checking and seeing only one thing about debugging is abled Android IceCream

-Tried the steps : http://www.androidcentral.com/ics-feature-mtp-what-it-why-use-it-and-how-set-it

But still there is no action on Ubuntu 14.04

My android version is Ice Cream Sandwich

I wonder

if there might be some device specific problem.

and can i set a debugging connection without USB connection
