我想在 Debian 稳定服务器上安装 OpenSSL 1.1.1a，该服务器目前已安装 OpenSSL 1.1.0j。因此，我根据此创建了必要的文件回答在/etc/apt/preferences.d文件夹中：stable.pref和testing.pref。之后，我将stable.list和添加testing.list到/etc/apt/sources.list.d文件夹中。
现在，当我尝试使用 安装较新的 OpenSSL 时sudo apt install openssl/testing，它会抱怨需要较新版本的libssl，因此需要较新版本的libc6。apt打印以下消息，这似乎不正确：
eloy@cyber:~$ sudo apt install libc6/testing

我该如何修复这个问题并从 Debian 测试存储库正确安装较新版本的 OpenSSL？或者这是正确的，我应该继续吗？我担心会损坏我的服务器。
答案1
通过使用修复了它sudo apt-get -t testing install openssl
eloy@cyber:~$ openssl version
