我的ubuntu是：
lsb_release -a
No LSB modules are available.
Distributor ID: Ubuntu
Description: Ubuntu 20.04.3 LTS
Release: 20.04
Codename: focal
更新：我终于发现，在安装过程中似乎有一些根本问题，因此我遇到了这些问题。。。所以我卸载docker使用：
sudo apt-get remove docker docker-engine docker.io containerd runc
然后我用稳定的脚本重新安装了Docker：
curl -fsSL https://get.docker.com -o get-docker.sh
DRY_RUN=1 sh ./get-docker.sh
