有一天我决定这样做apt update，结果收到了以下错误消息。我尝试用谷歌搜索并尝试了一些修复方法，但没有成功。想知道是否有人之前处理过这个问题或知道修复方法？
这里apt update输出：

不建议混合 Ubuntu 版本存储库。
sources.list 中的以下行是问题的根本原因：
http://security.archive.ubuntu.com/ubuntu precise-security main
precise从您的/etc/apt/sources.list或中删除存储库/etc/apt/sources.list.d/。
要获取名称文件并显示其内容，请使用：
grep -Rn --include=\*.list ^[^\#] /etc/apt/
