Describe the bug

Fails to install any apt-get packages on NIXPACKS v1.16.0, works on v1.15.0

/lib/x86_64-linux-gnu/libc.so.6: version `GLIBC_2.36' not found (required by /nix/store/xpxln7rqi3pq4m0xpnawhxb2gs0mn1s0-gcc-12.3.0-lib/lib/libstdc++.so.6)

Larger error from Railway Build logs:

#9 [stage-0 5/9] RUN apt-get update && apt-get install -y --no-install-recommends ffmpeg

#9 0.849 apt-get: /lib/x86_64-linux-gnu/libc.so.6: version `GLIBC_2.36' not found (required by /nix/store/xpxln7rqi3pq4m0xpnawhxb2gs0mn1s0-gcc-12.3.0-lib/lib/libstdc++.so.6)

Expected behavior

No response

Environment

On Railway, deploying a Flask app.

Is this just a standard flask app? Is there anything else being installed? Can you please share a minimal repo where it can be reproduced

[KastanDay]

• Yes, it's just a standard Flask app. Nothing fancy at all. Originally cloned from the official Railway template.
• No, there is nothing else being installed (no other apt-get installs). After the single apt-get install, we do a pip install -r requirements.txt, but that's unrelated to this bug.
• I'm too lazy to share a minimal repo, but here's a minimal railway.json. And here's my repo where it was failing.

Note v1.15.0 works, and v1.16.0 fails with the above error. The particular apt-get install does does not appear to matter, all the packages I tried (build-essential, ffmpeg, etc.) all fail with the same error.

I'm still hitting this issue with the latest nixpack version on Railway:

Here's all the logs that mention ffmpeg during build:

║ setup      │ python39, postgresql, pipenv, gcc, ffmpeg                       ║

#9 42.54 Setting up ffmpeg (7:4.4.2-0ubuntu0.22.04.1) ...

Then when ffmpeg gets called it errors out:

Output from ffmpeg/avlib:

ffmpeg: /lib/x86_64-linux-gnu/libc.so.6: version `GLIBC_2.36' not found (required by /nix/store/xpxln7rqi3pq4m0xpnawhxb2gs0mn1s0-gcc-12.3.0-lib/lib/libstdc++.so.6)

Edit: My nixpacks.toml is:

[phases.setup]
aptPkgs = ["...", "ffmpeg"]

[pfbyjy]

ran into this issue trying to install libreoffice as an aptPkg. The workaround was to install it as a nix package
