Install PHP Composer on Ubuntu
From WikiMLT
Install Composer via Apt
sudo apt update && \
sudo apt install composer
Depending on the version of the OS the Composer's version could be relatively old.
Install the latest version of Composer manually
sudo apt update
sudo apt install php-cli unzip
cd ~/tmp && \
curl -sS https://getcomposer.org/installer -o composer-setup.php && \
HASH=$(curl -sS https://composer.github.io/installer.sig) && \
php -r "if (hash_file('SHA384', 'composer-setup.php') === '$HASH') { echo 'Installer verified'; } else { echo 'Installer corrupt'; unlink('composer-setup.php'); } echo PHP_EOL;" && \
sudo php composer-setup.php --install-dir=/usr/local/bin --filename=composer && \
composer -V
