无法找到软件包 oracle-java8-installer linux mint

Question

我有

 java version "1.7.0_55"
OpenJDK Runtime Environment (IcedTea 2.4.7) (7u55-2.4.7-1ubuntu1~0.13.10.1)
OpenJDK 64-Bit Server VM (build 24.51-b03, mixed mode)

尝试通过以下命令将上述内容更新到最新版本：-

• sudo add-apt-repository ppa：webupd8team/java
• sudo apt-get 更新
• sudo apt-get install oracle-java8-installer

但是我收到以下错误：-

Reading package lists... Done

W: Duplicate sources.list entry http://dl.google.com/linux/chrome/deb/ stable/main amd64 Packages (/var/lib/apt/lists/dl.google.com_linux_chrome_deb_dists_stable_main_binary-amd64_Packages)

W: You may want to run apt-get update to correct these problems
E: Unable to locate package oracle-java8-installer

我什至尝试了这个链接：- Ubuntu：OpenJDK 8 - 无法找到软件包

我的爪哇路径：-

export JAVA_HOME=/usr/lib/jvm/java-7-openjdk-amd64
export PATH=$PATH:$HOME/bin:$JAVA_HOME/bin

谁能帮我这个，提前谢谢

Answer 1

你能尝试使用命令：apt-cache 搜索 oracle* 来搜索包名称是否存在。

Answer 2

这是在基于 Debian 的 Linux 上安装最新 JDK 的可靠方法。

echo "deb http://ppa.launchpad.net/webupd8team/java/ubuntu $(lsb_release -cs) main" > /etc/apt/sources.list.d/webupd8team-java-$(lsb_release -cs).list && echo oracle-java8-installer shared/accepted-oracle-license-v1-1 select true | /usr/bin/debconf-set-selections && apt-get update && apt-get install -y --allow-unauthenticated oracle-java8-installer && apt install -y oracle-java8-set-default
