如何修复错误“W：Target Packages …多次配置”？

我刚刚安装了Ubuntu Gnome 16.04。 我告诉它保存我的文件 – 哪个有效。 某些软件必须重新安装。 现在当我运行sudo apt-get update我看到了这个：

有没有自动解决方法？

最新的最新解决方案

我编写了一个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：

  1. 安装先决条件： 

     sudo apt install python3-apt

  2. 从最新版本下载ZIP包（ aptsources-cleanup.zip ）。

用法：

  1. sudo python3 -OEs aptsources-cleanup.zip

  2. 按照屏幕上显示的说明进行操作。

历史的，过时的解决方案

这是一个更老，更短，更简单的版本，更适合内联引用： 

 #!/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.')

它不需要参数，并且在python3-apt软件包的帮助下可以在所有/etc/apt/sources.list*上运行。 行不必是精确的重复（即使在标准化之后），但是如果类型，URI，套件和至少一个组件重叠则足够。

我不确定在所有极端情况下相等测试是否正确（例如各种“选项”字符串）。 请在GitHub上留下您的评论和分叉。

对我来说（16.04 LTS）去

系统设置>>软件和更新>>其他软件并从列表中删除每个重复的条目工作正常。

像这样重置您的存储库

  1. sudo rm /etc/apt/sources.list
  2. sudo software-properties-gtk
  3. 选择你的选择
  4. 保存

（PS我在将Ubuntu 15.10更新到Ubuntu 16.04之后今天遇到了同样的问题。）
