為什么 docker 在 manjaro 中不工作，連接被拒絕

Question

每個動作都會引發錯誤。

例如：

[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.

一些信息：

無論您等待多長時間，docker-desktop 都不會加載。只需 docker 桌面開始...

嘗試了來自不同來源的幾種方法，但沒有任何效果。

我正在使用 Manjaro，在啟動守護進程並將我的用戶放入 docker-group 后，一切都按預期工作（使用您特定的 docker 運行命令）。

但是，從您的錯誤消息來看，它看起來像是服務器 docker 存儲庫的連接問題。 您可以檢查您的防火牆是否連接被阻止。

這里有一個類似的案例，設置不同的 DNS 服務器似乎有效： why do i get this error when pulling an image in docker
