Unable to upgrade Android studio in Ubuntu
<p>I am currently using android studio 2.0 but  wanted to update it to 2.1 as its  been released on the stable channel. Now when I press on "Update &amp; Restart" button ,it downloads the patch and then will exit but wont restart by its own.So I am starting it manually to check if update was successful but it still shows android studio 2.0 and same dialogue "Android studio is ready to update". I did it many times but no success. I am using Linux  Ubuntu System 14.04 LTS.</p>
