Hi @johnnynunez and welcome to the community of fpdf2 users.

We would be happy to assist you in figuring out a solution to you problem 🙂

However you did not follow the issue report template: https://github.com/py-pdf/fpdf2/blob/master/.github/ISSUE_TEMPLATE/bug_report.md

A very important step is mentioned in this template:

Please include some minimal Python code reproducing your issue.
If you don't know how to build a minimal reproducible example, please check this tutorial: https://stackoverflow.com/help/minimal-reproducible-example

Without a mention of the version of fpdf2 that your are using, and some minimal code reprocing your problem, we will not be able to figure what's happening and help you!

We are getting the same error on our CI

Looks like an issue between endesive->oscrypto->openssl

[andersonhc]

A summary of what I could find:

• since last week "ubuntu-latest" runner is using ubuntu 24 instead of 22
• Ubuntu 22.04 includes OpenSSL 3.0.2
• Ubuntu 24.04 includes OpenSSL 3.0.13
• oscrypto 1.3.0 has a regex issue that can't handle OpenSSL version with more than 1 digit on the release version number. A fix was merged on the repository but a new version was never published on pypi

Thank you very much for the analysis @andersonhc 👍

I fixed the CI pipeline problem by pinning the GitHub Actions runner for now:
#1335

@johnnynunez: unless you want to provide further information regarding your issue, given that the CI pipeline problem has been solved, we will close this ticket at some point.
