我正在尝试使用 Docker 下载主页仪表板：
docker run -p 3000:3000 -v /path/to/config:/app/config -v /var/run/docker.sock:/var/run/docker.sock ghcr.io/gethomepage/homepage:latest
但我得到这个输出：
Unable to find image 'ghcr.io/gethomepage/homepage:latest' locally
docker: Error response from daemon: Get "https://ghcr.io/v2/": dial tcp 140.82.121.34:443: connect: network is unreachable.
See 'docker run --help'.
所以，我尝试了：
ping ghcr.io
不起作用，显示网络不可达。
我还尝试了 ping google.com，它确实有效，表明我仍然有一些互联网连接。
这是我的 ifconfig：

你能帮我解决这个问题吗？
我在Hetzner IPv6 only机器上遇到了同样的问题。错误的原因似乎是，ghcr.io 不提供 IPv6 AAAA DNS 记录。有一个 2023 年 11 月的未决问题提到了它。
我个人通过使用不同的镜像注册表解决了这个问题，在我的例子中是DockerHub，它允许自由托管公共镜像。
