英文:
Java 11 installation problem for Ubuntu 16.04
问题
我尝试了所有方法，但不知何故无法安装Java 11。显示我先前的Java版本。
我按照以下步骤操作：
步骤1： 我从Oracle网站安装了jdk-11.0.8_linux-x64_bin.deb文件。
步骤2： 运行此命令：sudo dpkg -i jdk-11.0.8_linux-x64_bin.deb
步骤3： 运行此命令：sudo get update
步骤4： 运行此命令：sudo vim /etc/profile.d/jdk.sh
步骤5： 在空文件夹中添加以下行：
export JAVA_HOME=/usr/lib/jvm/jdk-11.0.8/
export PATH=$PATH:$JAVA_HOME/bin
然后保存此文件。然后我在usr/lib/jvm路径下使用ls命令进行检查，我得到：
default-java@ java-1.8.0-openjdk-amd64@ java-8-openjdk-amd64/ jdk-11.0.8/
然后我执行了以下命令：
source /etc/profile.d/jdk.sh
我得到了以下输出：
set: 警告：路径组件 /usr/lib/jvm/jdk-11.0.8/bin:/home/duygu/bin 可能在PATH中无效。
set: 没有那个文件或目录
set: 你是不是想说 'set PATH $PATH /home/duygu/bin'？
...
当我检查java -version时，我得到：openjdk version "1.8.0_265"
然后我执行以下命令：update-java-alternatives --list，我得到：
java-1.8.0-openjdk-amd64 1081 /usr/lib/jvm/java-1.8.0-openjdk-amd64
我尝试了sudo reboot，然后再次尝试，但我仍未安装Java 11。我应该如何安装？我哪里出错了？
编辑：
我已经尝试了以下命令：
sudo add-apt-repository ppa:linuxuprising/java
sudo apt-get update
sudo apt-get install openjdk-11-jdk
我得到类似于以下的错误：
正在读取软件包列表... 完成
正在构建依赖关系树
正在读取状态信息... 完成
软件包 openjdk-11-jdk 是一个虚拟软件包，由以下提供：
oracle-java15-installer 15-1~linuxuprising3
oracle-java14-installer 14.0.2-1~linuxuprising1
oracle-java11-installer-local 11.0.8-1~linuxuprising0
你应该明确选择一个进行安装。
E: 软件包 'openjdk-11-jdk' 没有可安装的候选项

I've tried all the ways but somehow I can't install java 11.
Showing my previous version of java
I did following steps:
STEP 1: I Installed : jdk-11.0.8_linux-x64_bin.deb file from Oracle website.
STEP 2: Run this command : sudo dpkg -i jdk-11.0.8_linux-x64_bin.deb
STEP 3: sudo get update
STEP 4: run this command sudo vim /etc/profile.d/jdk.sh
STEP 5: Add this line in empty folder:
export JAVA_HOME=/usr/lib/jvm/jdk-11.0.8/
export PATH=$PATH:$JAVA_HOME/bin
And save this file. Than I checked in usr/lib/jvm path with ls
I get:
default-java@ java-1.8.0-openjdk-amd64@ java-8-openjdk-amd64/ jdk-11.0.8/
Than I enter this command:
source /etc/profile.d/jdk.sh
I get these output:

set: No such file or directory

When I check the java -version I get: openjdk version "1.8.0_265"
And enter this command : update-java-alternatives --list I get:
java-1.8.0-openjdk-amd64 1081 /usr/lib/jvm/java-1.8.0-openjdk-amd64
I tried sudo reboot and tried again and I didnt install java 11 . How can I install ? Where is my fault ?
EDITED:
I've already tried this lines:
sudo add-apt-repository ppa:linuxuprising/java
sudo apt-get update
sudo apt-get install openjdk-11-jdk
I get error like this:
Reading package lists... Done
Building dependency tree
Reading state information... Done
Package openjdk-11-jdk is a virtual package provided by:
oracle-java15-installer 15-1~linuxuprising3
oracle-java14-installer 14.0.2-1~linuxuprising1
oracle-java11-installer-local 11.0.8-1~linuxuprising0
You should explicitly select one to install.
E: Package 'openjdk-11-jdk' has no installation candidate

只需在安装后执行以下操作，
sudo nano /etc/environment
JAVA_HOME="/usr/lib/jvm/jdk-11.0.8"
注意，不要包括 /bin。保存并退出。然后，
source /etc/environment
顺便问一下，为什么要让正常安装变得复杂呢？
英文:
Just do this after installing,
sudo nano /etc/environment
JAVA_HOME="/usr/lib/jvm/jdk-11.0.8"
Note that, /bin is not to be included. Save and exit. Then,
source /etc/environment
Btw, why complicate a normal installation?

你可以使用以下命令安装Java 11：
sudo add-apt-repository ppa:linuxuprising/java
sudo apt-get update
sudo apt-get install openjdk-11-jdk
你可以参考这个链接了解如何在Ubuntu上安装OpenJDK 11。
然后，你可以运行以下命令来更新Java版本：
update-alternatives --config java
你可以参考这个链接了解如何更新Java备选版本。
英文:
You can probably install java 11 by the following command
sudo add-apt-repository ppa:linuxuprising/java
sudo apt-get update
sudo apt-get install openjdk-11-jdk
You can refer this link to see how to install openjdk 11 on ubuntu.
