Android Studio cannot update
This is probably because you do not have sufficient permissions.Try changing the owner of your studio installation folder.Try the following command.
sudo chown -R $USER:$USER /usr/bin/android-studio
if your using Ubuntu android 3.0v and getting error while updating to latest version and if you installed android studio using android installation guide example official video then you have to run sudo chown -R $USER:$USER /usr/local/android-studio/ this commend in your terminal
and make sure your android studio folder available in /local/ or any other folder and make necessary changes to /usr/etc path
go to android studio Click Help>>Check for update>> You will be told to run under root...a certain directory is given usr/local/etc/android-studio navigate to usr/local/etc/android-studio/bin ... Then run sudo sh studio.sh
--It will update as soon as you press enter...Hope it helps bro
