Hello! I’m a new user who has recently switched from macOS to Linux. I really enjoy using Fedora 35 on my oldish MacBook Air. It’s really performant! However, I have encountered an issue with a Python library that prevents me from developing my project.
I’m developing a Python (3.10.1) project that uses the pyppdf library. The pyppdf library depends on a puppeteer port – pyppeteer.
The pyppdf library uses puppeteer and runs headless chromium to generate PDFs from HTML. During the first run, pyppdf downloads a specific chromium version (86.0.4240.0).
Unfortunately, the HTML->PDF conversion never completes because chromium never launches (AFAIK) and my program is stuck until I stop it.
- I tried installing the suggested CentOS dependencies (some of them are not available for Fedora(?)): puppeteer/troubleshooting.md at main · puppeteer/puppeteer · GitHub
- I tried installing various
- I tried running the chromium instance that was downloaded by pyppdf. It throws errors and the GUI app is virtually not functional.

- I tried running the chromium instance downloaded by pyppdf with the following flags:
./chrome -v --no-sandbox --disable-setuid-sandbox. It throws the same errors but the GUI app is operable (websites are rendered). There’s also no way for me to pass these flags in my Python projects (I think).
- I downloaded the newest chromium and ran it from the terminal with no issues
My app and the pyppdf library work just fine on macOS and Ubuntu with the same Python interpreter version.
I guess that there must be something wrong with the dependencies or the way that Fedora handles older chromium versions.
I’d greatly appreciate your help! I googled a ton of threads before writing this post and found no solution.
