Pop!_OS / Ubuntu install

A small, idempotent installer that gets a fresh Pop!_OS 24.04 (or any Ubuntu 24.04 / Debian-derivative) to the state these dotfiles assume.

Two-tier strategy

Source	What lives there	Why
apt	`zsh`, `git`, `curl`, `build-essential`, `python3`, `python3-pip`, `python3-venv`, `luarocks`, `wl-clipboard`, `wezterm`, `brave-browser-beta`	System base, Mason prerequisites, and GUI vendor apps. Vendor apt repos auto-update Brave/WezTerm with `apt upgrade`.
Homebrew	`fzf` `fd` `bat` `eza` `zoxide` `ripgrep` `tmux` `neovim` `lazygit` `starship` `gh` `zsh-syntax-highlighting` `zsh-autosuggestions`	CLI toolchain. Ubuntu 24.04's apt versions are frozen at April 2024; brew always has latest. One `brew upgrade` updates all of them.
nvm	Node.js runtime	Installs the latest LTS release and sets it as the default; `.zshrc` sources `~/.nvm/nvm.sh`.
tpm	tmux plugin manager	Clone of `tmux-plugins/tpm` so the bundled `tmux.conf` works on first launch.

GitHub-release-binary downloads (the previous approach for nvim/lazygit/ starship) have been retired — they ran latest at install time then went stale. Brew solves that.

Environment required

Pop!_OS 24.04 (or Debian/Ubuntu derivative) — preflight aborts if apt-get is missing.
A regular user with sudo — not root.
Outbound HTTPS to apt.fury.io, brave.com, cli.github.com, github.com, raw.githubusercontent.com, and Ubuntu mirrors.

Install

git clone https://github.com/brianpooe/dotfiles.git ~/dotfiles
~/dotfiles/install/install.sh

Then open a new terminal (or log out + back in) so the new login shell takes effect.

Flags

install/install.sh                  # full install
install/install.sh --packages-only  # apt + brew + nvm + tpm, skip symlinks
install/install.sh --dotfiles-only  # symlink + chsh + tpm + nvm, skip packages
install/install.sh --help

Keeping current

update                  # alias: brew upgrade && sudo apt upgrade

The CLI tools come from brew, so they stay on bleeding-edge stable. Brave and WezTerm come from vendor apt repos so apt upgrade always has the latest of those too.

Layout

install/
  install.sh           entry point
  Brewfile             CLI toolchain bundle (brew owns these)
  lib/common.sh        helpers: apt_install, add_apt_repo, backup_and_link
  lib/packages.sh      apt base + WezTerm + Brave Beta vendor repos
  lib/brew.sh          install Homebrew + `brew bundle`
  lib/extras.sh        nvm + tpm
  lib/dotfiles.sh      symlink dotfiles + chsh zsh

What the installer does, in order

preflight — verify apt + not-root + sudo + curl.
apt base — system packages plus Mason's Python venv/pip and LuaRocks prerequisites.
WezTerm apt repo → apt install wezterm.
Brave Beta apt repo → apt install brave-browser-beta.
Homebrew install (NONINTERACTIVE) + brew bundle against Brewfile.
nvm (pinned $NVM_VERSION, default v0.40.1) + latest LTS Node.js.
tpm clone to ~/.tmux/plugins/tpm.
Symlink nvim tmux starship lazygit wezterm zed → ~/.config/...; .config/.ideavimrc → ~/.ideavimrc; .zshrc, .gitconfig → ~.
chsh login shell to zsh.

Pre-existing config targets get backed up to *.pre-install.<timestamp>, not deleted.
