bug: Fortress doesn't run on Debian 13

[juhacz]

What happened

I’m trying to run a program that uses Fortress on a Debian 13 VM via Proxmox. I’m getting the following error. On a regular computer with Win11, the program works fine.

Steps to reproduce

with Fortress(headless=False, channel="stable") as f:  # launches the stealth engine on a CDP endpoint
    with sync_playwright() as p:
        browser = p.chromium.connect_over_cdp(f.cdp_url)
        page = browser.new_page()
        page.goto("https://www.allegro.pl")
        input()
        page.screenshot(path="all-green.png")

Version

149.0.7827.232

Platform

Debian 13 VM
