Without this fix, you'll get:
```

Adding
`apt-get install -u php-mysql`
otherwise on startup you'll get an internal 500 error, with /tmp/logs showing:

"# FIX COMPOSER" entries have (probably) been copied-pasted twice from a terminal, with one truncated line at (hash_file('sha384', 'composer-setup.php')) that breaks the script
- update from php7.2 to php7.3
- includes fix for #20https://github.com/MISP/misp-docker/issues/20
- rewrites the REQUIREMENTS file to remove explicit versioning as they are for python2 packages, not python3
Modification of the file database.php to be able to give the possibility to a MISP to connect to a database with another user.
Addition to download the GPG key on the MISP homepage.
