application crashes due to missing library

error message while deploying: ./bin/rust-chlabs: error while loading shared libraries: libgssapi_krb5.so.2: cannot open shared object file: No such file or directory

my nixpack.toml

[phases.setup]

aptPkgs = ["libpq-dev", "libssl-dev", "pkg-config", "libkrb5-dev"]

so it's caused by diesel + postgres

i don't know what's wrong here, any help?
