我最近在旧电脑上安装了 Ubuntu 15.10。我现在正在尝试创建一个 windows usb 棒以安装在我正在构建的新计算机上。当我添加存储库时

    sudo add-apt-repository ppa:colingille/freshlight

我尝试更新，但出现以下错误：

    W: Failed to fetch http://ppa.launchpad.net/colingille/freshlight/ubuntu/dists/wily/main/binary-amd64/Packages  404  Not Found                         

    W: Failed to fetch http://ppa.launchpad.net/colingille/freshlight/ubuntu/dists/wily/main/binary-i386/Packages  404  Not Found

    E: Some index files failed to download. They have been ignored, or old ones used instead.

然后当我尝试：

   sudo apt-get install winusb

我得到：

   E: Unable to locate package winusb

谁能帮我找到解决办法？
