ls /etc/apt/sources.list.d/输出

我很困惑。有人对我如何更新我的系统有任何建议吗？

Answer 1

首先，保持sources.list.d的清洁，并删除所有不必要的东西。

第二，你为什么要使用个人包档案(PPA)？不要在Debian发行版中使用Ubuntu，因为包构建在Ubuntu库上，所以许多Launchpad PPA与Debian不兼容。

若要删除PPA，请执行以下操作：

add-apt-repository --remove ppa:whatever/ppa

此外，如果不需要deb-src行，则不需要它，deb行相对于二进制包，而deb-src相对于源包。这样你就可以摆脱它了。-如果这对你来说不重要的话，我个人不会移除它们

同时，Error 404是一个HTTP状态和响应代码，用于指示客户端能够成功地与服务器通信，但服务器无法找到所请求的任何内容。PPA与Debian并不完全兼容，我建议您删除它们，并尝试拥有必要的存储库。

这里是您需要并且应该在您的sources.list.d中拥有的东西，您的存储库并不存在，所以这就是为什么您没有找到错误404！

deb http://httpredir.debian.org/debian jessie main
deb-src http://httpredir.debian.org/debian jessie main

deb http://httpredir.debian.org/debian jessie-updates main
deb-src http://httpredir.debian.org/debian jessie-updates main

deb http://security.debian.org/ jessie/updates main
deb-src http://security.debian.org/ jessie/updates main

如果您还想要控制组件和非自由组件，请在main之后添加contrib非自由组件：

deb http://httpredir.debian.org/debian jessie main contrib non-free
deb-src http://httpredir.debian.org/debian jessie main contrib non-free

deb http://httpredir.debian.org/debian jessie-updates main contrib non-free
deb-src http://httpredir.debian.org/debian jessie-updates main contrib non-free

deb http://security.debian.org/ jessie/updates main contrib non-free
deb-src http://security.debian.org/ jessie/updates main contrib non-free

Answer 2

您需要删除其他派生存储库，因为它们与Debian不兼容：

添加一个ppa将创建两个文件：your_ppa.list和your_ppa.list.save

1)删除ppa：

sudo rm /etc/apt/sources.list.d/your_ppa.list

删除your_ppa.list.save

rm /etc/apt/sources.list.d/your_ppa.list.save

2)删除存储库的可信密钥：

首先，用gpg列出apt-key list键

使用以下方法从/etc/apt/trusted.gpg中删除密钥：

sudo apt-key del KEY_ID

更新您的包：sudo apt-get udate

示例：

#sudo apt-key list
 /etc/apt/trusted.gpg
--------------------
uid                  Oracle Corporation (VirtualBox archive signing key)   <info@virtualbox.org>
sub   4096R/920E471F 2016-04-22

关键是920E471F，要删除它，运行：

sudo apt-key del 920E471F
