apt 更新错误：存储库“http://us.archive.ubuntu.com/ubuntu saucy Release”没有发布文件

我在 Ubuntu 16.04 服务器上运行“sudo apt -y update”，但出现以下错误：

# apt -y update

原因可能是什么？我该如何解决这个问题？谢谢！

发生这种情况是因为您的机器上仍然有sources.listUbuntu 13.10的文件：

您可以sudo -i在终端中使用并将以下（完整块）复制并粘贴到其中：

cat > /etc/apt/sources.list << EOF
deb http://archive.ubuntu.com/ubuntu xenial main restricted universe multiverse
deb-src http://archive.ubuntu.com/ubuntu xenial main restricted universe multiverse
deb http://archive.ubuntu.com/ubuntu xenial-updates main restricted universe multiverse
deb-src http://archive.ubuntu.com/ubuntu xenial-updates main restricted universe multiverse
deb http://archive.ubuntu.com/ubuntu xenial-backports main restricted universe multiverse
deb-src http://archive.ubuntu.com/ubuntu xenial-backports main restricted universe multiverse
deb http://archive.ubuntu.com/ubuntu xenial-security main restricted universe multiverse
deb-src http://archive.ubuntu.com/ubuntu xenial-security main restricted universe multiverse
#deb http://archive.ubuntu.com/ubuntu xenial-proposed restricted main universe multiverse
#deb-src http://archive.ubuntu.com/ubuntu xenial-proposed restricted main universe multiverse
deb http://archive.canonical.com/ubuntu xenial partner
deb-src http://archive.canonical.com/ubuntu xenial partner
EOF

这将覆盖您的/etc/apt/sources.list文件。之后，您应该使用exit退出root。

如果您不希望启用所有软件包源，您可以从您在设置中找到的名为“软件和更新”的 GUI 小程序更改此设置。

那么你应该做强制性的：

sudo apt clean
sudo apt update
sudo apt dist-upgrade
