无法在 Ubuntu 18.04 上安装 OpenJDK 8

Question

我在我的系统上安装了 Ubuntu 18.04 的全新副本。现在我要安装 openjdk 8 包。结果出来了。

# apt install openjdk-8-jdk
Reading package lists... Done
Building dependency tree
Reading state information... Done
E: Unable to locate package openjdk-8-jdk

当我在 apt 缓存中搜索时，显示如下：

apt-cache search openjdk
default-jdk - Standard Java or Java compatible Development Kit
default-jdk-doc - Standard Java or Java compatible Development Kit (documentation)
default-jdk-headless - Standard Java or Java compatible Development Kit (headless)
default-jre - Standard Java or Java compatible Runtime
default-jre-headless - Standard Java or Java compatible Runtime (headless)
openjdk-11-dbg - Java runtime based on OpenJDK (debugging symbols)
openjdk-11-doc - OpenJDK Development Kit (JDK) documentation
openjdk-11-jdk - OpenJDK Development Kit (JDK)
openjdk-11-jdk-headless - OpenJDK Development Kit (JDK) (headless)
openjdk-11-jre - OpenJDK Java runtime, using Hotspot JIT
openjdk-11-jre-headless - OpenJDK Java runtime, using Hotspot JIT (headless)
openjdk-11-source - OpenJDK Development Kit (JDK) source files

有人知道哪里出了问题或遗漏了什么吗？

好的，我是通过阅读存储库文档自己发现的。

您应该可以使用任何列出的镜像，只需在您的 /etc/apt/sources.list 中添加一行，如下所示：

deb http://security.ubuntu.com/ubuntu 仿生安全主宇宙
