setup2

A bash script that sets up an Ubuntu machine for data science and software development.

Usage

Run as your normal user (not as root or with sudo; the script refuses to run as root). The script calls sudo itself when needed.

wget -qO- https://raw.githubusercontent.com/lab1702/setup2/main/install.sh | bash

What else it does

• Runs apt-get update and apt-get full-upgrade before installing. apt runs without prompts and keeps your existing config files when an upgrade ships new versions of them.

• The upgrade and install wait up to 10 minutes for the package lock if something else (like unattended-upgrades) holds it. apt-get update doesn't wait: if another update is running (common right after boot), the script stops, and you can run it again.

• Sets the npm global prefix to ~/.npm-global, on every run, replacing any other prefix in ~/.npmrc.

• Adds these lines to ~/.profile unless that setting is already there (commented-out lines don't count, and PIP_REQUIRE_VIRTUALENV set to any value counts and is kept):

  export PIP_REQUIRE_VIRTUALENV=1
  export PATH="$HOME/.npm-global/bin:$PATH"   # skipped if ~/.profile already adds ~/.npm-global/bin
  export PATH="$HOME/go/bin:$PATH"       # skipped if ~/.profile already adds ~/go/bin
  export PATH="$HOME/.cargo/bin:$PATH"   # skipped if ~/.profile already adds ~/.cargo/bin or sources ~/.cargo/env
  export PATH="$HOME/.local/bin:$PATH"   # skipped if ~/.profile already adds ~/.local/bin (Ubuntu's default does)

• Creates ~/.local/bin so Ubuntu's default ~/.profile puts it on your PATH.

• Adds eval "$(starship init bash)" to ~/.bashrc to turn on the starship prompt, unless ~/.bashrc already initializes starship.

• Warns you if a ~/.bash_profile or ~/.bash_login would stop login shells from reading ~/.profile, either because it doesn't source ~/.profile or because it can't be read.

• Adds you to the docker group so you can run docker without sudo.

• Tells you at the end whether a reboot is needed.

The script is safe to run again: it skips ~/.profile and ~/.bashrc settings that already exist, leaves those files untouched when there is nothing to add, and updates the stable Rust toolchain and DuckDB to their latest releases.

If ~/.profile or ~/.bashrc can't be read or written, the script leaves it as it is and prints a warning instead of stopping.

Notes

• Log out and back in after the first run for the docker group and the ~/.profile PATH changes to take effect.
• In SSH and console logins, Ubuntu's default ~/.profile runs ~/.bashrc before it reaches the PATH lines this script adds at the end, so commands in ~/.bashrc can't use programs from ~/.npm-global/bin, ~/go/bin or ~/.cargo/bin there. Desktop terminals aren't affected. To fix it, move those PATH lines above the part of ~/.profile that runs ~/.bashrc.
• fd-find installs its command as fdfind.
• Installing openssh-server starts SSH on port 22 with password logins allowed.

Requirements

Ubuntu 26.04 or later (amd64 or arm64). The script checks this and stops before changing anything on other systems.
