Describing my enviroment

My Laravel project is at the root of var/www, and i run the following commands to change folders permissions:

chown -R www-data:www-data /var/www
chmod -R 775 /var/www/storage

/etc/nginx/sites-enabled/default

server {
    listen 80 default_server;
    listen [::]:80 default_server;

    root /var/www/public;

    index index.php index.html index.htm index.nginx-debian.html;

    server_name advodocs.local.com;

    location / {
        try_files $uri $uri/ /index.php?$query_string;
    }

    location ~ \.php$ {
            try_files $uri =404;
            fastcgi_split_path_info ^(.+\.php)(/.+)$;
            fastcgi_pass unix:/var/run/php/php7.0-fpm.sock;
            fastcgi_index index.php;
            fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
            include fastcgi_params;
    }
}

Vagrantfile

Vagrant.configure("2") do |config|

    # Customiza propriedades do Vagrant
    config.vm.provider :virtualbox do |vb|
        vb.customize ["modifyvm", :id, "--memory", 2524]
        vb.customize ["modifyvm", :id, "--cpus", 1]
    end

    # Escolhe a box
    config.vm.box = 'ubuntu/trusty64'

    # Configura port forwarding
    config.vm.network :forwarded_port, guest: 80, host: 8080, auto_correct: true
    config.vm.network :private_network, ip: "192.168.68.20"

    #Inicia o provisionamento
    config.vm.provision :shell, :path => "provision/init.sh"
    config.vm.provision :shell, :path => "provision/php.sh"
    config.vm.provision :shell, :path => "provision/postgres.sh"
    config.vm.provision :shell, :path => "provision/nginx.sh"
    config.vm.provision :shell, :path => "provision/node.sh"
    config.vm.provision :shell, :path => "provision/git.sh"

    #Muda o dono de algumas pastas
    config.vm.synced_folder "./", "/vagrant",
    owner: "www-data", group: "www-data"

    config.vm.synced_folder "./", "/var/www",
    owner: "www-data", group: "www-data"

end

Obs: Laravel project is at the root of /var/www

Since you are running an Artisan command to make your controller, the command is trying to create your controller file through your ubuntu user but your ubuntu user doesn't have write permissions to your app folders to create the controller.

Let's say your ubuntu user is allan, do the following to solve this:

1. chown -R allan:allan /var/www
2. chown -R allan:www-data /var/www/storage
3. chmod -R 775 /var/www/storage
4. chown -R allan:www-data /var/www/bootstrap/cache
5. chmod -R 775 /var/www/bootstrap/cache

Now run your artisan command. It should work. If it doesn't, just check your /vagrant/storage/logs/laravel.log file and post the error

Alternatively, a quick and dirty way (that I don't recommend) is that you can just run your command through your www-data user like so: sudo su -s /bin/bash www-data and then run your Artisan command

I've just change my config.vm.synced_folder to:

config.vm.synced_folder "./", "/vagrant",
    owner: "vagrant", group: "www-data", mount_options: ["dmode=775,fmode=664"]
