Another issue when installing Laravel on the Ubuntu server is to make sure you have the mod_rewrite module enabled. You can turn it on by invoking the following command.
sudo a2enmod rewrite sudo service apache2 reload
Once you’ve enabled mod_rewrite, you need to restart Apache. That should fix any of the route issues that you may have. If mod_rewrite is disabled, you usually get 404 errors or file not found. The Laravel routes simply doesn’t work.
