Poem

🐰 I hopped in the script, made one tiny leap,
Swapped stable for unstable — a version to keep,
Lines barely changed, but the rabbit did sing,
New Neovim flavors — a brisk little spring! ✨

As of February 2, 2026, the ppa:neovim-ppa/unstable PPA does not publish packages for Ubuntu 20.04 (focal). On the PPA page, the selectable / published series are Jammy (22.04) and newer (Noble 24.04, Plucky 25.04, Questing 25.10, Resolute 26.04), with no Focal entry. [1]

Historically, there were focal builds in this PPA (e.g., recipe builds targeting the Focal series), but focal is not currently supported/published. [2]

NeoVim unstable PPA is incompatible with Ubuntu 20.04, a required supported version.

The ppa:neovim-ppa/unstable does not publish packages for Ubuntu 20.04 (focal). Switching from the stable PPA breaks the bootstrap script on Ubuntu 20.04, which is listed as a supported LTS version. Either:

1. Use ppa:neovim-ppa/stable for cross-version compatibility
2. Add logic to use stable PPA on Ubuntu 20.04 and unstable on newer versions
3. Remove Ubuntu 20.04 from supported versions

Pull request overview

This PR makes small style adjustments to arithmetic and redirection expressions and changes the Neovim APT repository used during bootstrap. The primary behavioral change is that Neovim will now be installed from the unstable PPA instead of the stable one.

Changes:

• Normalize spacing in redirections and arithmetic expansions in runCmdAndLog, startSpinner, and the elapsed-time calculation at the end of the script.
• Change the Neovim installation source from ppa:neovim-ppa/stable to ppa:neovim-ppa/unstable.

Switching from ppa:neovim-ppa/stable to ppa:neovim-ppa/unstable changes this step from installing the latest stable Neovim to tracking an "unstable" channel, which can introduce breaking changes or repository issues over time and makes bootstrap runs less predictable. If the intent is to get the newest features, consider either keeping the stable PPA and updating when needed, making the channel (stable vs unstable) configurable via a flag/env var, or clearly documenting that this script now depends on an unstable PPA so users understand the tradeoff.
