为什么在Ubuntu 18.04上无法安装oracle-java8-installer？

我正在尝试oracle-java8-installer使用以下命令在Ubuntu 18.04上安装：

apt-get update
apt-get install --yes --no-install-recommends software-properties-common && add-apt-repository ppa:webupd8team/java -y  && echo oracle-java8-installer shared/accepted-oracle-license-v1-1 select true | debconf-set-selections
apt-get install oracle-java8-installer

突然，这开始失败了：

“此文件最近被删除或移动过吗？” -它很可能不存在；您收到404错误。您可以通过浏览器将tar.gz下载到另一台计算机上吗？

这可能与：askubuntu.com/questions/966107/...

— davidvandebunte

我几乎可以保证，Oracle仅归档了Java 8 u191。Java 8当前更新为201。链接问题就是这种情况，因为您的使用尝试http://download.oracle.com/otn-pub已在不久前退出

— Ramhound

是的，我也同意这也是发生的事情

我们可以手动下载Java并轻松安装它。

下载Java 8版本： jdk-8u212-linux-x64.tar.gz

安装步骤：

  sudo mkdir /usr/local/java

  sudo tar xvzf jdk-8u212-linux-x64.tar.gz

  sudo mv jdk1.8.0_212 /usr/local/java/

  sudo update-alternatives --install "/usr/bin/javac" "javac" "/usr/local/java/jdk1.8.0_212/bin/javac" 1

  sudo update-alternatives --install "/usr/bin/java" "java" "/usr/local/java/jdk1.8.0_212/bin/java" 1

  sudo update-alternatives --install "/usr/bin/javaws" "javaws" "/usr/local/java/jdk1.8.0_212/bin/javaws" 1

  sudo chmod a+x /usr/bin/java
  sudo chmod a+x /usr/bin/javac
  sudo chmod a+x /usr/bin/javaws
  sudo chown -R root:root /usr/local/java/jdk1.8.0_212
  sudo update-alternatives --config java

安装成功后，请检查版本。

sudo java -version
