How to Install Emacs 26.2 in Ubuntu:

1. Open terminal either via Ctrl+Alt+T keyboard shortcut or by searching for “Terminal” from start menu. When it opens, run command to add the PPA repository:

sudo add-apt-repository ppa:kelleyk/emacs

Type user password (no asterisk feedback due to security reason) when prompts and hit Enter.

2. Then install Emacs26 either via Synaptic package manager, or by running following commands one by one in terminal:

sudo apt update

sudo apt install emacs26

For text-only interface, replace emacs26 with emacs26-nox in the last command. And Ubuntu 18.04 and higher can skip apt update command.

Once installed, open emacs from your system application launcher and enjoy!

How to Remove:

To remove Emacs26, open terminal and run commands:

sudo apt remove --autoremove emacs26 emacs26-nox

The PPA can be removed by going to Software & Updates -> Other Software tab.
