In the official repository, even Ubuntu 16.04 (the newest now) has only version 2.3 for NINJA IDE. If you want higher version than the official one, you can install it from PPA. We will use daily build PPA from NINJA IDE developer. Here the instruction how to do it.

How To Install

sudo apt-add-repository ppa:ninja-ide-developers/daily
sudo apt-get update
sudo apt-get install ninja-ide python-qscintilla2
Note: NINJA needs python-qscintilla2 to run properly. Without it, NINJA will be installed successfully but can't run.

How To Remove The PPA

sudo apt-add-repository --remove ppa:ninja-ide-developers/daily
sudo apt-get update
Note: this will remove the NINJA IDE PPA and then reload the repository configuration. This will not remove the NINJA IDE itself. Use this only when you don't need the PPA anymore.
