ProbeLabs65 findings · 95 requirements

A proof layer — requirements, tests and verified fixes — for two of Omarchy's subsystems: the application menu (launcher scripts, QML model, JSONC config, search and selection) and the lock screen (lock scripts, QML, PAM authentication). Scope is deliberately limited to those components of omacom/omarchy; the rest of the distribution is not covered.

Original report

Tailscale panel reports "CLI is not installed or not on PATH" when the which package is absentrevision 1 · captured 2026-09-28 21:29 UTC via poll

System details

Intel Core i5-9400F, NVIDIA RTX 4060 Ti (nvidia 580.178.04), Omarchy 4.0.0.r1772.gf32ebbd-1

What's wrong?

The Tailscale panel permanently shows "Tailscale CLI is not installed or not on PATH" on systems without the `which` package, even though Tailscale is installed, running, and connected.

Steps to reproduce

  1. On a system without which installed (pacman -Q which → not found; it's a standalone core/which package, not part of the Arch base install, and not in omarchy-base.packages or omarchy-other.packages).
  2. Install Tailscale and enable the widget: omarchy install tailscale + omarchy plugin enable omarchy.tailscale.
  3. Verify Tailscale actually works: tailscale status shows BackendState: Running and peers; the machine appears connected in the Tailscale admin console.
  4. Click the Tailscale panel in the bar → it shows "Tailscale CLI is not installed or not on PATH."

Root cause

shell/plugins/panels/tailscale/Service.qml detects the CLI by shelling out to the external which utility:

whichProcess.command = ["which", "tailscale"]

(line 155 on quattro at time of writing)

When which is absent, the command exits 127, installed stays false, and the panel reports the CLI as missing. The message points users at Tailscale/PATH while Tailscale itself is fine, which makes this genuinely confusing to diagnose.

The bash side of Omarchy already handles this correctly via the command -v builtin (omarchy-cmd-present), but a QML Process can't invoke a shell builtin without a shell. Since the plugin already shells out through bash -c elsewhere (copyToClipboard), something like this would work:

whichProcess.command = ["bash", "-c", "command -v tailscale"]

Workaround

omarchy pkg add which, then omarchy restart shell (or wait for the next refresh tick).

### What's wrong?

**The Tailscale panel permanently shows "Tailscale CLI is not installed or not on PATH" on systems without the `which` package, even though Tailscale is installed, running, and connected.**

#### Steps to reproduce

1. On a system without `which` installed (`pacman -Q which` → not found; it's a standalone `core/which` package, not part of the Arch base install, and not in `omarchy-base.packages` or `omarchy-other.packages`).
2. Install Tailscale and enable the widget: `omarchy install tailscale` + `omarchy plugin enable omarchy.tailscale`.
3. Verify Tailscale actually works: `tailscale status` shows `BackendState: Running` and peers; the machine appears connected in the Tailscale admin console.
4. Click the Tailscale panel in the bar → it shows **"Tailscale CLI is not installed or not on PATH."**

#### Root cause

`shell/plugins/panels/tailscale/Service.qml` detects the CLI by shelling out to the external `which` utility:

```qml
whichProcess.command = ["which", "tailscale"]
```

(line 155 on `quattro` at time of writing)

When `which` is absent, the command exits 127, `installed` stays `false`, and the panel reports the CLI as missing. The message points users at Tailscale/PATH while Tailscale itself is fine, which makes this genuinely confusing to diagnose.
