sudo apt install php-xml will work but the thing is it will download the plugin for the latest PHP version  If your PHP version is not the latest  then you can add version in it    PHP 7 1 sudo apt install php7 1-xml    PHP 7 2  sudo apt install php7 2-xml    PHP 7 3 sudo apt install php7 3-xml     PHP 7 4 sudo apt install php7 4-xml    PHP 8 sudo apt install php-xml

For whom want to install ext-dom on php 7 1 and up run this command   sudo apt install php-xml

User · Answer

First of all  read the warning  It says do not run composer as root   Secondly  you re probably using Xammp on your local which has the required php libraries as default    But in your server you re missing ext-dom  php-xml has all the related packages you need  So  you can simply install it by running   sudo apt-get update sudo apt install php-xml   Most likely you are missing mbstring too  If you get the error  install this package as well with   sudo apt-get install php-mbstring   Then run   composer update composer require cviebrock eloquent-sluggable
