如何修复“ W：目标软件包……配置了多次”的错误？

我刚刚安装了Ubuntu Gnome 16.04。我告诉它保存我的文档-可行。必须重新安装某些软件。现在，当我运行sudo apt-get update时，我会看到以下内容：

是否有一种自动的方法来解决此问题？

我看到了很多“解决方案”，但没有解释为什么会发生这种情况。

@PJBrunet这个问题没有问为什么，它要求他修复它。随意问一个新的问题，重点是为什么。

#1 楼

最近的最新解决方案
我编写了Python脚本来自动执行此任务。您可以在此处找到最新版本。
安装：

安装必备软件：

sudo apt install python3-apt

下载最新版本的PYZ捆绑包（aptsources-cleanup.pyz）。

将PYZ捆绑包标记为可执行文件：

chmod a+x aptsources-cleanup.pyz

用法：

从PYZ软件包的下载位置（请参阅上面的步骤2）运行：

sudo ./aptsources-cleanup.pyz

按照屏幕上显示的说明进行操作。

如果您想报告问题，发表评论或分叉源代码，请在GitHub上进行。

历史性的过时解决方案
这是一个更旧，更短，更简单的版本，更适合于内联引用：

 #!/usr/bin/env python3
"""
Detects and interactively deactivates duplicate Apt source entries.

Usage: sudo python3 apt-remove-duplicate-source-entries.py
"""

from __future__ import print_function
import aptsources.sourceslist

EMPTY_COMPONENT_LIST = (None,)

def get_duplicates(sourceslist):
    """
    Detects and returns duplicate Apt source entries.
    """

    sentry_map = dict()
    duplicates = list()
    for se in sourceslist.list:
        if not se.invalid and not se.disabled:
            for c in (se.comps or EMPTY_COMPONENT_LIST):
                key = (se.type, se.uri, se.dist, c)
                previous_se = sentry_map.setdefault(key, se)
                if previous_se is not se:
                    duplicates.append((se, previous_se))
                    break

    return duplicates


if __name__ == '__main__':
    try:
        input = raw_input
    except NameError:
        pass

    sourceslist = aptsources.sourceslist.SourcesList(False)
    duplicates = get_duplicates(sourceslist)

    if duplicates:
        for dupe, orig in duplicates:
            print(
                'Overlapping source entries:\n'
                '  1. {0}: {1}\n'
                '  2. {2}: {3}\n'
                'I disabled the latter entry.'.format(
                    orig.file, orig, dupe.file, dupe),
                end='\n\n')
            dupe.disabled = True

        print('\n{0} source entries were disabled:'.format(len(duplicates)),
            *[dupe for dupe, orig in duplicates], sep='\n  ', end='\n\n')
        if input('Do you want to save these changes? (y/N) ').upper() == 'Y':
            sourceslist.save()

    else:
        print('No duplicated entries were found.')

它不带任何参数并且可以正常工作在所有/etc/apt/sources.list*上借助python3-apt软件包。行不必完全相同（即使在归一化之后）也可以，但是如果类型，URI，套件和至少一个组件重叠，则行就足够了。
我不确定在所有极端情况下均等测试是否正确（例如各种“选项”字符串）。

您可以从终端通过命令wget“github.com/davidfoerster/aptsources-cleanup/releases/download/…”下载它。

@Sami：是的，但是当我发布另一个版本时，它将不再指向最新版本。

我从第1行收到SyntaxError：语法无效，从zip运行脚本。克隆git仓库并从那里运行可以。

对我来说（16.04 LTS）转到

系统设置>>软件和更新>>其他软件，然后从列表中删除每个重复的条目都很好。

我要求一种自动方法。

这是比执行它之前阅读国外python3脚本更好的解决方案。。。

您可以删除具有不同类型的“重复项”吗？例如，我有http://ppa.launchpad.net/ubuntu-toolchain-r/test/ubuntu xenial main和http://ppa.launchpad.net/ubuntu-toolchain-r/test/ubuntu xenial main（源代码）。是否可以删除一个（源代码）（而不选择另一个，而不检查另一个）？

@Tim是真的，但这可能不是大多数人来问这个问题的原因

@Deruijter说“源代码”的代码不被视为与另一个代码的重复。但是，除非您想下载某些软件包的源代码以自行编译它们，否则不需要显示“源代码”的代码。

重设存储库，如下所示：

重要信息：首先验证是否已安装software-properties-gtk（可以运行software-properties-gtk -h以验证是否获得帮助消息）
sudo mv /etc/apt/sources.list /etc/apt/sources.list.bak
sudo software-properties-gtk
选择选项
保存

一旦一切正常，您就可以使用sudo rm -rf /etc/apt/sources.list.bak删除备份。

请注意，只有在检查并确保您的系统上确实安装了software-properties-gtk后，您才应该这样做。不要问我是什么让我写了这个。

打开software-properties-gtk后，我看不到任何重复项。我在Ubuntu 20.04 LTS上。

由于错误会告诉您问题出在哪里，并且所有问题都是由一条重复的行引起的，因此您可以使用vim，nano等文本编辑器轻松手动修复此问题。这样做的好处是您可以准确看到问题是什么以及要解决的问题。

对于您的情况，使用sudo或以root身份在文本编辑器中打开/etc/apt/sources.list。删除第33行或第87行。您可以直观地检查它们是否是重复项。

如果您喜欢vim ...

$ sudo vim /etc/apt/sources.list
33 [Shift]+g    # to goto line 33
87 [Shift]+g    # to goto line 87, don't need a duplicate of line 33
dd              # to delete the line you're on
:wq             # to write the file and quit

或者，如果遇到错误，请走出去...

:q!             # to quit without saving any changes

我在/etc/apt/sources.list.d/google-cloud-sdk.list中遇到了类似的问题。这对我有用。谢谢！

谷歌浏览器类似的问题。两个.list文件中的条目相同，我使用此方法在其中一个中删除。

对于具有Linux Mint的基于Ubuntu的系统，请转至软件源>维护>删除重复的软件包

这样做我没有发现重复，但仍然看到相同的错误
