How to Install Alacritty terminal emulator in Ubuntu Linux

This app is not available in Ubuntu system repository until the next Ubuntu 23.04. User can install it via 2 methods: cargo package manager, or third-party Ubuntu PPA.

Option 1: Install Alacritty via cargo package manager

Cargo is the command line package manager for Rust, like Pip for Python. User can use the tool to install Alacritty terminal emulator in most Linux, though user needs to MANUALLY setup PATH variable and create shortcut icon.

1. First, press Ctrl+Alt+T on keyboard to open terminal. When it opens, run command to install cargo:

sudo apt install cargo

Type user password (no asterisk feedback) when it asks and hit Enter to continue.

2. Then, install Alacritty for current user only by running command:

cargo install alacritty

3. As mentioned, cargo package does not add PATH variable by default. You can verify by running $PATH command and see if “/home/USERNAME/.cargo/bin” present in the output.

To add it into user PATH, run command nano ~/.profile to edit user profile and add following lines:

if [ -d "$HOME/.cargo/bin" ] ; then

When done, press Ctrl+X, type y and hit Enter to save change! NOTE: user PATH changes take effect at next login.

4. The cargo package also does not create shortcut icons. Meaning you need to manually create one by running command:

nano ~/.local/share/applications/alacritty.desktop

Then paste following lines and save it:

[Desktop Entry]

Comment=A fast, cross-platform, OpenGL terminal emulator

[Desktop Action New]
Name=New Terminal

Finally, either use alacritty command or search for and launch it from start menu (or ‘Activities’ overview).

Option 2: Install Alacritty in Ubuntu via PPA

An Ubuntu PPA can be more easy to install the terminal emulator for beginners. Though, it seems to be unofficial.

NOTE: The PPA package at the moment includes Alacritty 0.13.0 development, though the package name marked as 0.12.0 stable.

So far the PPA supports for Ubuntu 20.04, Ubuntu 22.04, Ubuntu 22.10, Ubuntu 23.04 and their based systems.

1. First, open a terminal window and run command to add the Ubuntu PPA:

sudo add-apt-repository ppa:aslatter/ppa

Type user password (no asterisk feedback) when it asks and hit Enter to continue.

2. Linux Mint and few Ubuntu based systems may need to manually update the package index, though it’s done automatically in Ubuntu since 20.04:

sudo apt update

3. Finally, install Alacritty terminal emulator via command:

sudo apt install alacritty

Once installed, search for and launch it from start menu or ‘Activities’ overview, or by running alacritty command.

Uninstall Alacritty terminal emulator

To remove the package installed via Cargo, open terminal and run command:

cargo uninstall alacritty

Also remove the shortcut icon if added via command:

rm ~/.local/share/applications/alacritty.desktop

For choice, you may also remove the Cargo package manager, though other apps installed through Cargo will also be removed:

sudo apt remove cargo

To remove the package installed from Ubuntu PPA, use command:

sudo apt remove --autoremove alacritty

Also remove the Ubuntu PPA via command:

sudo add-apt-repository --remove ppa:aslatter/ppa

That’s all. Enjoy!

Gnome Console terminal emulator added new tab overview feature a few days ago by releasing version 44 beta.

For those never heard of Gnome Console, it’s new core application for GNOME desktop since version 42. Gnome Console formerly called kgx, has a more modern and native look and feel than the previous Gnome Terminal. Ubuntu proposed to use Gnome Console as default terminal emulator in 22.10 release, but delayed due to few regressions.

Gnome Console has an attractive feature that the header bar turns red when running sudo command or switching to root user. And, it goes purple for remote / ssh terminals.

With the most recent Gnome Console 44 Beta release, it has a new “Show All Tabs” option under the hamburger menu (≡).

NOTE: For version 44 with new tab overview feature, you need Ubuntu 23.04 / Fedora 38 which are still in development stage, or Arch/Manjaro with unstable repository.
