I've been attempting to help a user in the forums[1] with an issue running Docker rootless - he's running into an issue with being able to pull images resulting in the following error: Error response from daemon: Get "https://registry-1.docker.io/v2/": dial tcp: lookup registry-1.docker.io on 10.0.2.3:53: read udp 10.0.2.100:48971->10.0.2.3:53: i/o timeout He also opened a discussion in the Docker forums (who referred him to our forums), and I've been chatting with the guy (Ákos) who was helping him over there in that thread[2]. The puzzling thing for me is that I can't duplicate the issue. I've tried on GNOME and KDE both, and I just cannot reproduce the problem. In troubleshooting the issue together with Ákos, we seem to have isolated the issue to something in the slirp4netns network that's used in that configuration - but nobody involved has customized that setup at all - yet it fails for both of them and doesn't fail for me. The issue *seems* to be that the DNS server set up in that network (10.0.2.3) is not responsive for either of them - but it is for me. Wondering if anyone here has any ideas about what else to look at beyond what we already have in these two threads. I'm completely out of ideas.
