W: You may want to run apt-get update to correct these problems

我一次又一次地更新apt-get，它显示了警告。我使用的是ubuntu12.04lts和我的内核信息。 Linux siva-pt130 3.2.0-23-generic＃36-Ubuntu SMP Tue Apr 10 20:39:51 UTC 2012 x86_64 x86_64 x86_64 GNU / Linux

Answer 1

您的/etc/apt/sources.list文件包含重复项。用像vim这样的编辑器打开它并删除它。再次运行apt-get update。

Answer 2

我认为virtualbox会创建新的列表文件夹，因此您可以使用以下命令将其删除：

sudo rm -rf /etc/apt/sources.list.d/virtualbox.list
sudo rm -rf /etc/apt/sources.list.d/virtualbox.list~

然后运行：

sudo apt-get update

运行命令sudo apt-get update时发出警告
