`nix-store --load-db` crashes on kasm docker images

In a kasmweb/ubuntu-jammy-desktop:1.14.0 docker container running as root:

$ curl --proto '=https' --tlsv1.2 -sSf -L https://install.determinate.systems/nix -o nix-installer
$ chmod a+x nix-installer

Here's a dockerfile to repro:

FROM kasmweb/core-ubuntu-jammy:1.14.0
USER root
RUN curl --proto '=https' --tlsv1.2 -sSf -L https://install.determinate.systems/nix/tag/v0.15.1 | sh -s -- install linux --init none --no-confirm

Got it to not crash by setting ENV LD_LIBRARY_PATH "". However when calling nix I get https://github.com/DeterminateSystems/nix-installer/issues/777

[mausch]

This works:

FROM kasmweb/core-ubuntu-jammy:1.14.0
USER root
RUN echo 'ALL ALL=(ALL) NOPASSWD: ALL' >> /etc/sudoers
USER 1000
ENV LD_LIBRARY_PATH ""
RUN curl --proto '=https' --tlsv1.2 -sSf -L https://install.determinate.systems/nix/tag/v0.15.1 | sh -s -- install linux --init none --no-confirm
ENV PATH="$PATH:/nix/var/nix/profiles/default/bin"
RUN sudo chown --recursive kasm-user /nix # https://github.com/NixOS/nix/issues/3435#issuecomment-1642654775

It's unclear to my why nix-store --load-db would fail without printing to stderr. It's also unclear to me how setting LD_LIBRARY_PATH solves your issue...

If your workaround is to chown /nix you may want to consider the single user scripts: https://nixos.org/manual/nix/stable/installation/installing-binary#single-user-installation
