我正在尝试使用安装 curl
apt-get install curl
但它产生了错误：
Err:1 http://security.ubuntu.com/ubuntu xenial-security/main amd64 curl amd64 7.47.0-1ubuntu2.12
404 Not Found
Err:1 http://security.ubuntu.com/ubuntu xenial-security/main amd64 curl amd64 7.47.0-1ubuntu2.12
404 Not Found
E: Failed to fetch http://security.ubuntu.com/ubuntu/pool/main/c/curl/curl_7.47.0-1ubuntu2.12_amd64.deb 404 Not Found
我的想法：
我提到本文，然后我意识到自从我的版本 16.04 LTS 以来，它仍然受支持，并且这不是问题。
我也读过这个问题，但这两个答案都不适用于我的情况（apt-get update失败并且xenial-security存在于http://security.ubuntu.com/ubuntu/dists/）。
接下来我访问了 URLhttp://security.ubuntu.com/ubuntu/pool/main/c/curl，我发现curl_7.47.0-1ubuntu2.13_amd64.deb而不是curl_7.47.0-1ubuntu2.12_amd64.deb，这是 所请求的apt-get。因此，我推断apt-get应该请求2.13而不是2.12，因此得名。
但是，我有点被困在这里。我不确定下一步该怎么做才能解决这个问题，我很感激任何建议。

答案1
sudo apt-get update解决了 Charles 评论中指出的这个问题。在我的具体案例中，通过引用这个问题，运行sudo rm /var/lib/apt/lists/partial/*使得sudo apt-get update执行成功。
