I am trying to correct the icon and the display name of Arduino IDE in my launcher. I used to lock on the sketch of Arduino IDE 1.6.3 in 7 April into the launcher. It didn't work as I expected so I removed it and I reinstalled the old version of Arduino IDE with this command:
sudo apt-get update && sudo apt-get install arduino arduino-core
The problem here is whenever I opened the Arduino IDE, it still showed me the name of sketch and Arduino 1.6.3 instead of just Arduino IDE.
How to remove the old one and correct the display icon here!
