这是我第一次在我的系统上安装linux，我觉得这里有很多乱七八糟的东西，当我尝试更新系统时遇到太多错误，当我使用带有此命令的终端时，我感到无助：
sudo apt update
我从这三种类型中得到了很多错误：
知道我搜索了很多主题但无法用我的系统解决问题。
这是我写完“sudo apt update”后得到的输出

答案 0 :(得分：3)
输出只是一个警告，警告您在main sources.list文件和名为google-chrome.list的特殊文件中具有相同的条目。 您可以使用它或删除它，因为它是不需要的。
为此，请打开终端并运行
sudo rm /etc/apt/sources.list.d/google-chrome.list
然后运行
sudo apt-get update
然后运行
sudo apt-get upgrade
希望对您有帮助。
答案 1 :(得分：2)
我遇到了类似的问题，这是多次显示的错误
W: Target Packages (non-free/binary-amd64/Packages)
is configured multiple times in /etc/apt/sources.list:51
and /etc/apt/sources.list.d/opera-stable.list:4
我以这种方式解决了
在终端中输入以下命令
sudo nano /etc/apt/sources.list
注释掉引起问题的行。
保存您的更改。
答案 2 :(得分：1)
repository update命令的错误/警告输出与您的存储库设置有关。设置位于/etc/apt/sources.list.d/<file>和/etc/apt/sources.list内。
首先，您应该注释掉位于 cdrom 的所有存储库，因为您真的不想使用CD-ROM安装媒体中的软件包......
其余错误与不安全连接（普通HTTP）或只是存储库已死（404，发布文件）有关。您可能应该使用与 cdrom 相同的内容 - 将它们注释掉。
答案 3 :(得分：-1)
或者...只需关闭您的VPN。运行
sudo apt更新
这应该给您正常的结果。似乎VPN和代理几乎干扰了更新。
