请帮帮我！！我被困了 3 天，无法在我的 ubuntu 18.04 上安装 java；什么都没用 :-(；因为我的信息很少，虽然我尝试过 oracle.com>java14 安装程序套件>下载 tar.gz 文件>无法设置它。以下是详细查询：
apt --fix-broken install 不起作用，sudo apt autoremove 和 dpkg 都说未安装，但在安装时它说 dpkg 已经有更新版本::
adrino@Inspiron:~$ sudo apt-get update

答案1
您想要实现什么？我看到 Java 11 软件包和 Java 14 软件包上都存在错误。您想要安装哪个版本？无论如何：我的建议是完全删除所有 Java 软件包，然后尝试安装您想要的版本。
我发现两个问题，一个是 ，oracle-java14-installer另一个是openjdk-11-jre。您说您尝试通过从 Oracle 下载 .tar.gz 文件来安装 Java，但您遇到的问题似乎不相关。
第一个问题是。这似乎来自PPA 的oracle-java14-installer软件包oracle-java14-installer_14.0.2-1~linuxuprising1http://ppa.launchpad.net/linuxuprising/java/ubuntu。这是您自己添加的 PPA。尝试使用 删除该包sudo apt-get --purge remove oracle-java14-*。
的输出sudo apt autoremove显示The following packages have unmet dependencies: default-jdk : Depends: openjdk-11-jdk default-jre : Depends: openjdk-11-jre。在我看来，这像是openjdk-11-jre缺少包。安装时会发生什么？sudo apt update先执行 ，然后执行sudo apt install openjdk-11-jre。现在 的输出sudo apt autoremove没有错误了吗？
