Ubuntu - Install Composer

Manual Installation (Current Preferred)

Install composer manually with the chained command below to ensure you have the latest version, which you may need to do if you are using PHP 8.

sudo apt update \
  && sudo apt install curl -y \
  && curl -sS https://getcomposer.org/installer | php \
  && sudo mv composer.phar /usr/bin/composer \
  && sudo chmod +x /usr/bin/composer

Alternatively you can install through prog-exec:

prog-exec "21/1" "9821b9b31fecd498b8454eed4331e1048ffd51c48dfc906e3707bbdd43665830"

Native Packages

You can now install composer using the local ubuntu packages with:

sudo apt update
sudo apt install composer -y

Now you can run all the composer commands from any directory, such as:

composer update
