![我无法在 Ubuntu 18.04 LTS 上安装 JRE 和 JDK](https://linux22.com/image/1156768/%E6%88%91%E6%97%A0%E6%B3%95%E5%9C%A8%20Ubuntu%2018.04%20LTS%20%E4%B8%8A%E5%AE%89%E8%A3%85%20JRE%20%E5%92%8C%20JDK.png)
我无法同时安装 JRE 和 JDK。首先,我没有尝试安装 JDK,但我认为如果我这样做了,它不会起作用,因为您需要安装 JRE。
其次,我无法安装 JRE,我已经按照很多教程操作了,例如https://www.lifewire.com/install-java-on-ubuntu-4125508,并且java
和javac
命令不起作用。它说,Command 'java' not found, but can be installed with: ...
我不确定openjdk
是什么。请帮帮我。
PS 我也搜索过询问 Ubuntu 的问题,但是都没有帮助。

编辑/PS 对于那些认为这是重复的人,你错了。我没有使用虚拟机,我试了又试,直到成功,而且确实成功了。我现在的问题是,没有安装 JDK。我在安装 NetBeans 时发现了这一点,没有安装 JDK,但安装了 JRE。
答案1
JDK 包含 JRE,因此您只需要 JDK 即可。
您的终端会话显示您的 Oracle Java 8 JDK 安装程序下载已损坏 ( sha256sum mismatch jdk-8u171-linux-x64.tar.gz
)。要修复问题并重新安装:
sudo rm /var/cache/oracle-jdk8-installer/*.tar.gz
sudo apt-get update
sudo apt-get install --reinstall oracle-java8-installer
答案2
如果安装了jdk,就不需要安装jre。
如果你这样做会发生什么
sudo apt-get install default-jdk
