+title: 'Fixing GitHub Copilot CLI System Vault Error with systemd'
+pubDate: 2026-01-02
+author: 'Nakahara Daisuke'
+tags: ["GitHub", "AI"]
+---
+
+When installing GitHub Copilot CLI, you may encounter the error message: `The system vault (keychain, keyring, password manager, etc.) is not available. You may need to install one.` The solution was documented in [this issue](https://github.com/github/copilot-cli/issues/49).
+
+This article explains how to resolve this issue using `systemd`.
+
+### Install via Apt
+
+```bash
+$ sudo apt update
+```
+```bash
+$ sudo apt install -y \
+  gnome-keyring \
+  libsecret-1-0 \
+  libsecret-tools \
+  seahorse
+```
+
+### Verify systemd is running
+```bash
+$ systemctl is-system-running
+```
+
+### Check if the user service is enabled
+```bash
+$ systemctl --user status gnome-keyring-daemon
+○ gnome-keyring-daemon.service - GNOME Keyring daemon
+     Loaded: loaded (/usr/lib/systemd/user/gnome-keyring-daemon.service; enabled; preset: enabled)
+     Active: inactive (dead)
+TriggeredBy: ○ gnome-keyring-daemon.socket
+```
+```bash
+$ systemctl --user enable gnome-keyring-daemon
+```
+```bash
+$ systemctl --user start gnome-keyring-daemon
+```
+```bash
+$ systemctl --user status gnome-keyring-daemon
