Hello everyone 👋, You may encounter an issue when installing Passbolt on a fresh environment when using `nginx` with `ssl` enabled, and more specifically when running an `nginx` version prior to 1.25.1. This is due to a recent change we made to our `nginx-ssl.conf` template, where we swapped the way we enable the `http2` module from the now deprecated `listen [::]:443 ssl http2;` to the new [HTTP2 directive](https://nginx.org/en/docs/http/ngx_http_v2_module.html#http2). Unfortunately, this directive was introduced with `nginx` version 1.25.1, which isn’t available by default on certain distributions, such as Debian 12 (oldstable) and Ubuntu 24.04 LTS. As a workaround while we publish a fix for this issue, you can edit the configuration file located under `/etc/passbolt/nginx-ssl.conf`, comment the `http2 on;` line and add `http2` at the end of both `listen` directives. This configuration file should look like this once done: ```auto # Managed by Passbolt listen [::]:443 ssl http2; listen 443 ssl http2; # http2 on; ``` Thank you for your understanding, The Passbolt packaging team ---
