后来我查了下，这种404错误大多是因为本地的软件源缓存过期，或者默认的官方源访问不稳定导致的，试了下面几个方法解决了，给同样碰到这个问题的朋友参考：

• 第一步：更新软件源缓存
  先执行sudo apt update命令，刷新本地的包索引，获取最新的包地址信息，这样可以避免因为旧索引里的地址已经失效而出现404。

• 第二步：如果更新缓存后还是报错，尝试更换软件源
  可以把默认的Ubuntu源换成国内常用的镜像源，操作步骤如下：

  1. 先备份原来的源文件：sudo cp /etc/apt/sources.list /etc/apt/sources.list.bak
  2. 编辑源文件：sudo nano /etc/apt/sources.list，把文件里的内容替换为适配当前Ubuntu版本的国内镜像源内容
  3. 保存退出后，再次执行sudo apt update刷新缓存

• 第三步：重新执行安装命令
  等缓存更新完成后，再运行sudo apt install openjdk-11-jdk-headless，应该就能正常安装了。
