apt get update 缺少发布文件

做完之后apt-get-更新我总是收到这些错误信息：

Reading package lists... Done

N: Data from such a repository can't be authenticated and is therefore potentially dangerous to use.

我读到一篇帖子说应该更改 /etc/apt/sources.list 的内容（见下文）。哪些行需要注释掉？

我已经通过添加它们测试了 ppa，它也显示了与您发生的相同错误：

W: The repository 'http://ppa.launchpad.net/ubuntu-audio-dev/ppa/ubuntu xenial Release' does not have a Release file.
N: Data from such a repository can't be authenticated and is therefore potentially dangerous to use.
N: See apt-secure(8) manpage for repository creation and user configuration details.
E: Failed to fetch http://ppa.launchpad.net/ubuntu-audio-dev/ppa/ubuntu/dists/xenial/main/binary-i386/Packages  404  Not Found

如果你去他们的启动板 ppa 页面，你会看到 ppa 不再可用，如 13.10 (Saucy Salamander)，这会导致404 Not Found错误：

在此处输入图片描述

为了消除错误，只需删除 ppa：

sudo add-apt-repository --remove ppa:ubuntu-audio-dev/ppa
sudo apt-get update
sudo apt-key del 72B194E5

更新

对于There is no public key available错误，请在终端上运行以下命令：

sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys 1397BC53640DB551

对于 Google Chromein Release file错误，请执行以下步骤：

  1. 打开一个新的终端窗口并运行以下命令：

    sudo gedit /etc/apt/sources.list.d/google-chrome.list

  2. 在打开的文本文件中编辑该文件，使行内容如下：

    deb [arch=amd64] http://dl.google.com/linux/chrome/deb/ stable main

  3. 点击保存。关闭 Gedit 窗口。
