Unable to download composer

Easy way
Try the easy way first. The hard way was included in this answer because of the error messages mentioned in the comments.
sudo mkdir -p /usr/local/bin
sudo apt-get install curl
curl -sS https://getcomposer.org/installer | php
sudo mv composer.phar /usr/local/bin/composer
In Ubuntu 16.04 and later composer can be installed from the default Ubuntu repositories. Open the terminal and type:
sudo apt install composer
Hard way
First check if /usr/local/bin/
exists, and if not make the /usr/local/bin/
directory.
sudo mkdir -p /usr/local/bin
If /usr/local/bin/
already exists, the above command will do nothing except return this message:
mkdir: cannot create directory ‘/usr/local/bin’: File exists
Run these commands:
sudo chmod -R 755 /usr/local/bin/
cd /usr/local/bin/
ls # list the old composer file(s)
sudo rm <old-composer-files> # delete the old composer file(s)
sudo apt-get install curl
curl -sS https://getcomposer.org/installer | php
sudo mv composer.phar /usr/local/bin/composer
Then if you type composer
in the terminal it will be accessible globally in your system.
