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

ran into the same issue when I used coolify

What packages were you trying to install? This can happen if the packages expect an older version of glibc. The issues from 2023 have been fixed and were related to Nixpacks using an older version of Python.

@coffee-cup I am not sure about that since Coolify automate the generation of nixpacks.toml file, I got over the issue when I switched to Docker with coolify.
