FAQ

VIBE module frequently asked questions.

Deployment

code-server package not found

Make sure that NODE and the repository configuration are ready:

yum repolist    # EL
apt-cache policy   # Debian/Ubuntu, read-only inspection
./infra.yml -l infra -t repo --check

JupyterLab installation failed

jupyter_venv must exist:

uv venv /data/venv
./vibe.yml -l <host> -t jupyter --check
./vibe.yml -l <host> -t jupyter

Access

Cannot access `/code/` or `/jupyter/`

Check service status
Check port listening
Check Nginx config

systemctl status code-server
systemctl status jupyter
ss -tlnp | grep 8443
ss -tlnp | grep 8888
nginx -t

WebSocket connection fails

Ensure Nginx enables WebSocket (default is enabled). If using custom infra_portal, set websocket: true.

Password and Token

Change Code-Server password

First, save the new password in the inventory. This keeps it out of shell history:

./vibe.yml -l <host> -t code_config,code_launch --check
./vibe.yml -l <host> -t code_config,code_launch

Change JupyterLab token

First, save a high-entropy random token in the inventory. The current template allows any Origin and disables XSRF checks. Never use an example token or expose TCP/8888 directly:

./vibe.yml -l <host> -t jupyter_config --check
./vibe.yml -l <host> -t jupyter_config
ssh <host> sudo systemctl restart jupyter

Claude Code

CLI not found

First check whether claude_install completed:

which claude
npm list -g --depth=0 | grep '@anthropic-ai/claude-code'
./vibe.yml -l <host> -t claude_install

If claude_enabled is disabled, install manually:

npm install -g @anthropic-ai/claude-code

Use claude_package to select a different npm package.

Codex CLI not found

which codex
npm list -g --depth=0 | grep '@openai/codex'
./vibe.yml -l <host> -t codex_install

Confirm that codex_enabled: true. VIBE installs only Codex CLI. It does not generate the Codex configuration.

API key not set

export ANTHROPIC_API_KEY=sk-ant-xxx
# or set in claude_env

Telemetry not showing

Check local VictoriaMetrics/VictoriaLogs:

curl http://127.0.0.1:8428/api/v1/status/buildinfo
curl http://127.0.0.1:9428/select/logsql/stats_query

Ensure OTEL endpoints in ~/.claude/settings.json are correct.

Extensions and Plugins

Code-Server extension install fails

Check network
Try switching code_gallery
Or install VSIX manually

code-server --install-extension /path/to/extension.vsix

JupyterLab extension install fails

source /data/venv/bin/activate
pip install jupyterlab-git
systemctl restart jupyter
