它显示第 46 行，deb http://archive.canonical.com/ubuntu xenial partner但我看不出有什么问题。它可能partner包括第一个 .deb 行中的一些内容。
发生错误时
我有软件资源
现在，没有这样的警告
注意，出于某种原因，同一个字段出现了两次。这里我们想了解为什么会出现这样的警告，或者为什么有两个这样的字段。
答案1
只需删除该/etc/apt/sources.list.d/xenial-partner.list文件即可解决错误。
sudo rm /etc/apt/sources.list.d/xenial-partner.list
这就是重复输入错误的根源，您已/etc/apt/sources.list启用文件中的两行，并且在此之前，中的行/etc/apt/sources.list.d/xenial-partner.list。
为了进一步了解该文件的来源，正如您在评论中询问的那样，您可能需要查看https://answers.launchpad.net/ubuntu/+question/294476
答案2
这就是那行代码存在的原因，它是源代码，而不是普通人日常使用的应用程序。
之所以有 2 个条目，是因为其中一个是源，另一个是构建的应用程序。
至于另一个答案，我建议把它们留在那里，不要移除。如果它没坏，就不要修理它！
