Error for new Project about magento2

Seems like your Composer folder is restricted, use these commands out of the Docker container, inside the folder created on your machine.

./stop && ./kill && sudo chmod -R 777 ~/.composer && rm -rf ./src && mkdir ./src && ./start && ./shell

So, you can run again install-magento2.

Please let me know if it's working well!

Interesting... I am having the exact same issue on a different repo
markshust/docker-magento#80

I have tried to change ownership of composer folder, but with no success...

Try running these commands to remove and recreate the folders.

Out of the container:

sudo rm -rf ./var/composer_home ./composer.lock ./vendor

Inside the container:

mkdir /var/www/html/vendor/
composer install
