How to Install Emacs 24.4 in Ubuntu:
At the moment of writing this tutorial, there’s no PPA repository that contains Emacs 24.4. Fortunately, it’s not hard to build it from the source tarball. I’ve done it successfully in 64-bit Ubuntu 14.04 LTS. Below steps will show you how:
1. If have the old Emacs 24.3 installed, you may first remove it from Ubuntu Software Center so that you can install the new version over it.
2. Press Ctrl+Alt+T on keyboard to open terminal, or open it from the Unity Dash.
3. Run command below to install the build-essential:
sudo apt-get install build-essential
4. Install the required dependencies:
sudo apt-get build-dep emacs24
While the installing process, you’ll be asked to configure the Postfix.
5. Now download Emacs 24.4 from its official FTP download page.

6. Extract the source and go into the result folder in terminal:
cd ~/Downloads && tar -xf emacs-24.4.tar.* && cd emacs-24.4
7. Finally compile the package by running commands below one by one.
sudo make install
Once done, you should be able to launch Emacs by running
emacs-24.4 in terminal and lock the shortcut to the Unity Launcher.
To create a launcher for Emacs 24.4. Thanks to Emad Khoury, run command to create a .desktop file and edit it with Gedit text editor:
sudo gedit /usr/share/applications/Emacs-24.desktop
When the file opens, paste below into it and save the file.
Exec=env UBUNTU_MENUPROXY=0 /usr/local/bin/emacs

Depends on where you install Emacs 24, you may replace the value of Exec and Icon to the path to executable and shortcut icon file.
