I have gone through all of the previous threads, including all of the suggestions in the Completely Uninstall Android Studio thread, about uninstalling Android Studio and followed their directions and nothing helps. I installed Android Studio with the Standard installation but for a tutorial I'm following I need a Custom installation. I tried deleting the `/android-studio` folder along with the hidden `/.android` folder in my home directory and then re-extracting the folder from the original .zip file from [here](https://developer.android.com/studio/install.html) however every time I re-run the studio.sh file from my terminal it immediately restarts as was without re-installing. I have tried

```
sudo apt-get remove android-studio

```

and it tells me it cannot find the package. I've also tried every possible answer I've found so far including installing ubuntu-make and ppa:purge and nothing works. I can't even search for android studio in my task manager bar. I'm working on Ubuntu 16.04.
