How to install Emacs 29.1 in Ubuntu:
GNU Emacs editor is easy to install in Ubuntu Linux with few different ways. Choose any one that you prefer!
Option 1: Snap package
For Ubuntu 20.04, Ubuntu 22.04 and higher, simply launch Ubuntu Software, then search and install GNU Emacs from Snap Store. Though, it’s a Snap package runs in sandbox.
Option 2: Ubuntu PPA
For those prefer the classic
.deb package format, Debian upstream has built the new release package. And, I backported it into this PPA with support for for Ubuntu 22.04, Ubuntu 20.04 and Ubuntu 23.04.
NOTE: The PPA package is just no-change backport without testing! It may or may not work in your case!
First, press Ctrl+Alt+T on keyboard to open terminal. When it opens, run command to add the PPA:
sudo add-apt-repository ppa:ubuntuhandbook1/emacs
Type user password (no asterisk feedback) when it asks and hit Enter to continue.
Then, either open Software Updater (Update Manager) to upgrade the package if an old version was installed.
Or, run the command below instead to install/update the Emacs package:
sudo apt install emacs emacs-common
Linux Mint user needs to run
sudo apt update first to manually refresh package cache.
Option 3: Flatpak package
Emacs is also available to install as Flatpak package. Though, at the moment of writing, the package is still at v28.2. Check it HERE.
Uninstall Emacs 29.1
For the snap package, also use Ubuntu Software to remove it. Or, run command in terminal:
sudo snap remove --purge emacs
For the package installed from Ubuntu PPA, open terminal (Ctrl+Alt+T) and run command:
- purge the PPA as well as downgrade Emacs to stock version:
sudo apt install ppa-purge && sudo ppa-purge ppa:ubuntuhandbook1/emacs
