我目前正在尝试在 Databricks 上运行一些 R 代码。一些 R 包要求我安装 libcurl4-openssl-dev。我在尝试安装 libcurl4-openssl-dev 时收到以下错误：
Ign:1 http://archive.ubuntu.com/ubuntu focal-updates/main amd64 libcurl4-openssl-dev amd64 7.68.0-1ubuntu2.15
Err:1 http://security.ubuntu.com/ubuntu focal-updates/main amd64 libcurl4-openssl-dev amd64 7.68.0-1ubuntu2.15
404 Not Found [IP: 185.125.190.39 80]
E: Failed to fetch http://security.ubuntu.com/ubuntu/pool/main/c/curl/libcurl4-openssl-dev_7.68.0-1ubuntu2.15_amd64.deb 404 Not Found [IP: 185.125.190.39 80]
E: Unable to fetch some archives, maybe run apt-get update or try with --fix-missing?
我之前尝试过apt-get update安装软件包，但没有帮助。问题似乎是它试图寻找 7.68.0-1ubuntu2.15而最新版本似乎是 7.68.0-1ubuntu2.16
在再次尝试安装之前，我也尝试运行以下命令：
sudo apt --fix-missing update
sudo apt update
sudo apt install -f
也没有帮助。任何关于如何安装 libcurl4-openssl-dev 的建议都将非常有帮助。谢谢！
编辑：
sudo apt update输出如下

apt-cache policy libcurl4-openssl-dev输出如下
libcurl4-openssl-dev:

不确定软件包的安装顺序是否重要，但我想无论如何还是要在这里提一下。以下是我正在尝试的：
apt-get update
apt-get install -y make libnode-dev libgdal-dev gdal-bin libgeos-dev libproj-dev libsqlite3-dev libpng-dev libudunits2-dev libicu-dev
sudo apt --fix-missing update
sudo apt update
sudo apt install -f
apt-get install -y libssl-dev libcurl4-openssl-dev pandoc
如果我尝试apt install libcurl4-openssl-dev上述操作，我会得到以下结果，但现在已经过去了 15 分钟，命令还没有运行完成。不确定这是否应该花这么多时间。当我发布此更新时，它仍在运行。

解决方案 下面的方法似乎有效，但我并不完全确定为什么。我对 Linux 还很陌生，所以我对此不太了解。我想在这里提到它，以便它可以帮助其他人。如果这里有人可以解释为什么会发生这种情况，那就太好了！

当我在添加存储库后尝试安装 libcurl4-openssl-dev 时，我可以毫无问题地安装它。如果我尝试在不添加存储库的情况下执行此操作，则会收到错误。我很高兴找到了解决方案，但很想知道为什么我需要这样做。为什么它不从一开始就搜索“focal-updates main”？每次我需要安装软件包时，我都应该这样做吗？
