ubuntu初始化登录jenkins提示Error错误

安装环境：

jdk使用的是二进制安装的jdk11

https://www.oracle.com/java/technologies/downloads/#java11

jenkins使用的是jenkins2.2774(deb包)版本

https://mirrors.jenkins-ci.org/debian-stable/

安装好daemon和jdk后，服务正常启动浏览器初始化界面出现如下错误：

root@ubuntu1804:~# apt install daemon -y

配置文件中带有-Djava.awt.headless=true这个参数，所以不是这个问题；
