Access to APT repository and ability to install Debian packages with it.: Apt repository check failure (sudo -S apt-get update && sudo -S apt-get check).
E: The repository 'cdrom://Ubuntu 18.04.5 LTS _Bionic Beaver_ - Release amd64 (20200806.1) bionic Release' does not have a Release file.

你这个是sdkmanager里面的sdk和组件都被误删了吧，你卸载掉，重新安装一遍sdkmanager再刷机，确保系统环境是Ubuntu16.04
