# Updating

> Update agents to the latest version.

## Automated Update

Run the update script on the server:

```bash theme={null}
curl -sSL https://your-control-plane.com/update.sh | sudo bash
```

The script:

1. Downloads the latest agent binary from GitHub releases.
2. Verifies the SHA256 checksum.
3. Replaces the existing binary.
4. Restarts the systemd service.

No configuration or dependencies are changed during an update.

## Manual Update

Download the binary for your architecture:

```bash theme={null}
# For x86_64
curl -fsSL https://github.com/techulus/cloud/releases/latest/download/agent-linux-amd64 \
  -o /usr/local/bin/agent
chmod +x /usr/local/bin/agent

# For arm64
curl -fsSL https://github.com/techulus/cloud/releases/latest/download/agent-linux-arm64 \
  -o /usr/local/bin/agent
chmod +x /usr/local/bin/agent
```

Restart the service:

```bash theme={null}
sudo systemctl restart techulus-agent
```

## Verify

Check that the agent is running after the update:

```bash theme={null}
sudo systemctl status techulus-agent
sudo journalctl -u techulus-agent -n 20
```
