I'm trying to install Magento 2.3.3 on Debian 9 over a virtual machine.

I'm stuck during the magento installation process because of the magento-composer-installer plugin. I also did a manual installation using the following command from the magento devdocs, but I always get the same error:

composer --no-ansi --no-interaction install --no-progress --prefer-dist --optimize-autoloader

Loading composer repositories with package information
Installing dependencies (including require-dev) from lock file
    Finished: success: 0, skipped: 0, failure: 334, total: 334
Package operations: 460 installs, 0 updates, 0 removals
  - Installing magento/magento-composer-installer (0.1.13): Loading from cache
Plugin installation failed, rolling back
  - Removing magento/magento-composer-installer (0.1.13)

  Could not delete /home/vagrant/magento/magento2/vendor/magento/magento-composer-installer/src/MagentoHackathon: 

I'm using Windows 10 as host machine.

Composer 1.9.2
PHP 7.2
Vagrant 2.2.6
Virtual Box 6.0.16

Do you have any idea how to resolve that error? I saw a similar question here, but no really relevant answer.

I finally found a solution here while disscussing with the virtual machine's developer.
