New install - openssl_pkey_new(): Private key length must be at least 384 bits, configured to 0

[tigerdjohnson]

I am building a new LNMS instance from scratch on Ubuntu 22.0.4.3. When I get to the point of installing php dependencies, I receive the following error:

> LibreNMS\ComposerHelper::postInstall
Script LibreNMS\ComposerHelper::postInstall handling the post-install-cmd event terminated with an exception

In ECKey.php line 93:

  openssl_pkey_new(): Private key length must be at least 384 bits, configured to 0

w/–vvv

Environment:

1. Ubuntu 22.0.4.3 LTS (VMware if it matters)
2. OpenSSL 3.0.2
3. PHP 8.1.23
4. Python 3.10.12
5. MariaDB 10.6

To replicate:

1. Install Ubuntu 22.04.3
2. apt update/upgrade & reboot
3. Follow lnms installation instructions to the point of installing PHP dependencies
4. Run ./scripts/composer_wrapper.php install --no-dev
5. Error

I’ve replicated the issue on Debian 12: PHP 8.2.10, OpenSSL 3.0.9, python3 3.11.2, mariadb 10.11.3-1

Any ideas?

While transferring the previous host’s SSL certs/key, I accidentally overwrote the default openssl.cnf file with a cnf that was intended for csr only. I restored the default deb/ubuntu /etc/ssl/openssl.cnf and all is good.
