为什么 docker 在 manjaro 中不工作，连接被拒绝

Question

Every action throws an error.

For example:

[greenjoy@greenjoyPC ~]$ docker run hello-world
Unable to find image 'hello-world:latest' locally
docker: Error response from daemon: Get "https://registry-1.docker.io/v2/": dial tcp: lookup registry-1.docker.io on [::1]:53: read udp [::1]:50383->[::1]:53: read: connection refused.

Some information:

And docker-desktop won't load no matter how long you wait.Just docker desktop starting...

Tried several ways from different sources but nothing works.

I am using Manjaro and after starting the daemon and putting my user into the docker-group everything works as expected (using your particular docker run command).

However, from your error message, it rather looks like a connectivity problem to the server docker repositories. You may check on your firewalls whether connections are blocked.

There is a similar case here, where setting a different DNS server seemed to work: why do i get this error when pulling an image in docker
