我最近自动删除了旧的未使用的内核。在过程结束时，它输出此消息：
W: Duplicate sources.list entry http://dl.google.com/linux/talkplugin/deb/ stable/main amd64 Packages (/var/lib/apt/lists/dl.google.com_linux_talkplugin_deb_dists_stable_main_binary-amd64_Packages)
W: Duplicate sources.list entry http://dl.google.com/linux/talkplugin/deb/ stable/main i386 Packages (/var/lib/apt/lists/dl.google.com_linux_talkplugin_deb_dists_stable_main_binary-i386_Packages)
W: You may want to run apt-get update to correct these problems
所以我运行了，sudo apt-get update但最后还是收到了同样的消息。所以我再次运行，仍然收到了同样的消息。
我现在应该怎么做？

您的源列表中存在重复项。如果您不小心两次添加了同一个存储库，通常会发生这种情况。签出并检查/etc/apt/sources.list内容是否有重复项。/etc/apt/sources.list.d/
