Answer 1

Install the following dependency:

sudo apt-get install php7.1-xml

You can try refer the issues here: PHP7 : install ext-dom issue

Answer 2

Your screenshot says: "phpunit required ext-dom" ..

That means, you have to install PHP-XML extension in order to get phpunit and Laravel properly installed.

Answer 3

You are missing the correct extension for PHP try installing

sudo apt-get install php7.1-dom

You may also need to install other packages to get everything to update.

Take a look at this link may help you https://askubuntu.com/questions/795629/install-php-extensions-in-ubuntu-16-04

Answer 4

You are missing ext-dom , php7.1-xml has the packages you need, try installing it by running:

sudo apt-get update
sudo apt-get install php7.1-xml

Then run this command:

composer install

If you don't have a composer you can follow this link from Digital Ocean which is very clear.
