シェルからapt-getのログ出力

私はapt-getgoプログラムでvia execを使用しています。このように：

func aptInstall(pkg, ver string) {
    args := []string{"install", "-y", fmt.Sprintf("%s=%s", pkg, ver)}
    cmd := exec.Command("apt-get", args...)
    cmd.Env = append(os.Environ(), "LANG=en")
    out, err := cmd.CombinedOutput()
    log("apt install", "cmd", fmt.Sprintf("apt-get %s",
        strings.Join(args, " ")), "out", string(out), "err", err)
}

記録されたメッセージには以下が含まれます。

インタラクティブモードで実行されていないことをどのように知り、apt-get進行メッセージを表示しないのですか（Reading database ...ANSI-ESCカラーを追加しないでください）。

修正する

両方の答えを試しましたが、色はセットごとに削除されましたが、TERM=dumb進捗情報はまだ残ります。

-qqqyほとんどの出力メッセージは表示されませんが、apt-get install機能しないようですapt-get remove。
