Before installing this package,
please download the Oracle JDK 11 .tar.gz file
with the same version as this package (version 11.0.4),
and place it in /var/cache/oracle-jdk11-installer-local,
E.g.:
sudo mkdir -p /var/cache/oracle-jdk11-installer-local
sudo cp jdk-11.0.4_linux-x64_bin.tar.gz /var/cache/oracle-jdk11-installer-local/
sha256sum mismatch jdk-11.0.7_linux-x64_bin.tar.gz
Oracle JDK 11 is NOT installed.

问题到底是什么？Jankins 需要哪个 Java 版本？我相信 Java-13 是一个相当新的版本，并且 Java 完全向后兼容。
答案1
我认为 Jenkins 正在尝试寻找 Oracle JDK 11。这写在上面的消息中
未安装 Oracle JDK 11。dpkg
：错误处理程序包 oracle-java11-installer-local（--configure）：
子进程安装的安装后脚本返回错误退出状态 1
如果你正在安装 Jenkins，请在安装 Jenkins 之前安装 JDK 11。请按照以下适用于 Ubuntu 20.04 的教程进行操作
OpenJDK 安装
案例 - 2
如果安装了 Jenkins 并且它异常退出，exit code 1并且当您尝试获取状态时systemctl status jenkins.service，您会得到以下输出
