Question

我在系统上安装了Ubuntu 18.04的新副本。现在，我将安装openjdk 8软件包。追随者出来了。

# apt install openjdk-8-jdk

E: Unable to locate package openjdk-8-jdk

当我在apt缓存中搜索时，将显示以下内容：

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

有人知道出什么问题了吗？

好吧，我是通过阅读存储库文档自己找到的。

通过在/etc/apt/sources.list中添加一行，您应该能够使用任何列出的镜像，如下所示：

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

无法在Ubuntu 18.04上安装OpenJDK 8
