系统Ubuntu 20.04.我已经重新安装了Docker至少两次。我总是用sudo运行docker-compose。

$ sudo service docker status
● docker.service - Docker Application Container Engine
     Loaded: loaded (/lib/systemd/system/docker.service; enabled; vendor preset: enabled)
     Active: active (running) since Fri 2023-07-21 09:18:05 EDT; 8min ago

$ ps |grep docker

$ sudo docker-compose up
ERROR: Couldn't connect to Docker daemon at http+docker://localhost - is it running?

字符串
我做错了什么？
