https://code-server.dev/install.sh selects Fedora instead of Debian

[TiemenSch]

Is there an existing issue for this?

• I have searched the existing issues

OS/Web Information

• Web Browser: n.a.
• Local OS: n.a.
• Remote OS: Debian
• Remote Architecture: amd64
• code-server --version: latest
• docker-image: python:3-slim

I tried installing code-server in a Dockerfile using https://code-server.dev/install.sh on the official Python docker image python:3-slim and the install script thought it was Fedora based instead of Debian (it's bookworm).

I ended up mixing and matching install snippets from the website and the install.sh contents, which probably is slightly better practice anyway:

RUN CODER_VERSION="$(curl -fsSLI -o /dev/null -w "%{url_effective}" https://github.com/coder/code-server/releases/latest)" \
    && CODER_VERSION="${CODER_VERSION#https://github.com/coder/code-server/releases/tag/}" \
    && CODER_VERSION="${CODER_VERSION#v}" \
    && mkdir -p ${HOME}/.cache \
    && cd ${HOME}/.cache \
    && curl -fOL https://github.com/coder/code-server/releases/download/v${CODER_VERSION}/code-server_${CODER_VERSION}_amd64.deb \
    && dpkg -i code-server_${CODER_VERSION}_amd64.deb \
    && rm -rf ${HOME}/.cache

Distro detection seems to need a patch, though.

Steps to Reproduce

1. FROM python:3-slim
2. RUN curl -fsSL https://code-server.dev/install.sh | sh

I had to add curl but it seems to work as expected for me using that image. Here is what I did:

$ mkdir -p tmp
$ cat <<EOF >> tmp/Dockerfile
FROM python:3-slim
RUN apt update && apt install curl -y
RUN curl -fsSL https://code-server.dev/install.sh | sh
EOF
$ docker build -t code-server ./tmp
