Failed to copy Bridge app

Error message

Failed to copy Bridge app

What it means

After the mkdir step, deploy_remote copies the bridge app with `scp -r -- <bridge_dir> <user@host>:~/ArduinoApps/` and bails when scp exits non-zero. The connection was good enough to attempt the copy, but the transfer itself failed.

Solutions

1. Inspect the board: `ssh arduino@<host> 'df -h ~ && ls -la ~/ArduinoApps'`
2. Clean the previous copy: `ssh arduino@<host> 'rm -rf ~/ArduinoApps/uno-q-bridge'` and rerun the setup
3. If transfers keep dying mid-way, check the network link to the board and retry

let df = std::process::Command::new("ssh")
    .args(["--", &format!("arduino@{host}"), "df", "-Pk", "~/ArduinoApps"])
    .output()?;
// fail early if the board's home filesystem is full
let text = String::from_utf8_lossy(&df.stdout);
if !text.contains('/') { anyhow::bail!("cannot stat ~/ArduinoApps on board"); }

match setup_uno_q_bridge(Some(host)) {
    Err(e) if format!("{e}").contains("Failed to copy Bridge app") => {
        // clean ~/ArduinoApps/uno-q-bridge on the board, free disk, retry once
    }
    rest => rest,
}

When it happens

Trigger: Disk full under the remote home directory; permission problems inside ~/ArduinoApps (e.g. an earlier root-owned copy); the connection dropping mid-transfer; the remote ArduinoApps directory disappearing between steps.

Common situations: Small onboard filesystems filling up after repeated deploys; a previous failed deploy leaving partial or root-owned files; flaky Wi-Fi links to the board.
