Question

I am using ubuntu 16.04, laravel 5.2 when i run update composer in my project directory its showing \"the requested PHP extension dom is missing from your system\" i checke

Answer 1

DOM is a PHP extension and not a PHP package. This means that your version of PHP needs to be recompiled with the extension. It is possible however that your PHP was already compiled with DOM but that DOM is not enabled. You can check this in your php.ini (search for extension=dom.so and make sure it's uncommented).
