我正在尝试安装 BigBlueButton，目前为止一切正常（sudo bbb-conf --status 将所有部分标记为活动状态）。但是使用存储库的 docker 安装失败（sudo apt-get install docker-ce docker-ce-cli containerd .io）。
Setting up docker-ce (5:20.10.3~3-0~ubuntu-xenial) … Job for
docker.service failed because the control process exited with error
code. See “systemctl status docker.service” and “journalctl -xe” for
details. invoke-rc.d: initscript docker, action “start” failed.

我试了好几天了。卸载并删除了 Docker 页面上显示的所有内容（“卸载 Docker”）。有些人也遇到过类似的问题，但我找到的解决方案对我没有用。
提前致谢！问候
/编辑：我正在使用全新安装的 Ubuntu Server 16.04。（BigBlueButton 必备）。我安装了一个 GUI（xfce4）。
/edit2：“有时我们会被问到‘为什么你们只支持 Ubuntu 16.04 64 位？’”答案是基于选择质量而不是数量。很久以前，我们就得出结论，对于项目来说，拥有一个稳定、经过充分测试、有据可查的特定版本的 Linux 安装，并且运行得非常好，比尝试支持许多 Linux 变体，但都无法很好地运行要好。”这就是 BBB 安装所说的。
答案1
好吧，伙计们，我放弃了。它只支持 16.04，我自己也找不到错误 :´( 无论如何，谢谢你们的回答 :)
