PHP Composer for jailed user

OS type and version Ubuntu Linux 20.04.6
Webmin version 2.021
Usermin version 1.861
Virtualmin version 7.7
Theme version 20.21
Package updates All installed packages are up to date

I try to setup a global composer so that each user at the server can use it by default.
To set it up I did this:

First install composer as root to /usr/local/bin

php -r "copy('', 'composer-setup.php');"
php -r "if (hash_file('sha384', 'composer-setup.php') === '55ce33d7678c5a611085589f1f3ddf8b3c52d662cd01d4ba75c0ee0459970c2200a51f492d557530c71c15d8dba01eae') { echo 'Installer verified'; } else { echo 'Installer corrupt'; unlink('composer-setup.php'); } echo PHP_EOL;"
php composer-setup.php --install-dir=/usr/local/bin/ --filename=composer
php -r "unlink('composer-setup.php');"

In /etc/jailkit/jk_init.ini I’ve added this at the end

comment=PHP Composer

Then I’ve rebooted the Server.
But if I login as a jailed ssh-user, I still can not find any composer to use.


I’ve also tried to add composer to an existing jailed user with command:

jk_init -c /etc/jailkit/jk_init.ini -f -k -j /home/chroot/16769902463484203/usr/bin/ composer

The jailed user has this content in $PATH: /usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin
Without luck.

Any Idea what’s missing?
