On the first few occasions it seemed to me that my local network could be at fault, but it's _almost_ reliably reproducable in qemu, virtualbox and even on bare metal and is not limited to myself (check the channel logs with some good search queries). So it might be worth looking into. The installed system does not have this problem after a reboot.

A little more information: I was installing on i686 bare metal from the current USB installation image. I installed vim in the installation environment, and then when I tried to run `guix system init...` I couldn't resolve hydra.gnu.org, google.com, and a few other sites. I could resolve the domain famulari.name, but not another domain that points to the same machine. I installed dig and could successfully query the nameserver described in /etc/resolv.conf for hydra.gnu.org. I never have name resolution problems on this network with my other machines. I decided to edit /etc/hosts so I could continue with the installation. If anyone has any ideas about how to debug this, I'm happy to help.

Have you > tried restarting the nscd service? That sounds likely. Nscd caches negative lookups, but normally only for 20 seconds (see %nscd-minimal-caches in (gnu system install)). So if you look up hydra.gnu.org before the network is set up, it=E2=80=99ll remember for 20s = that this is a lookup failure, even if you=E2=80=99ve set up the network in the meantime. However, nscd is reportedly behaving strangely: . Do you initially get successful lookups for hydra.gnu.org, and eventually lookup failures? Ludo=E2=80=99.

Yes, that's at least in my case precisely what happens. It works for the first few packages during system init, and then at some point in time fails. I'll try to reproduce and then restart the nscd to see if it helps (when I find time to do it)..

Commit c96ba2c disables caching of lookup failures altogether. Could you try again to reproduce it? (I think Florian wrote in the initial bug report that this was reproducible in QEMU, so using =E2=80=98guix system vm gnu/system/install.scm=E2=80=99 might suffice.) Alternately we could remove nscd altogether, but I think it=E2=80=99s still somewhat useful to cache successful lookups. TIA, Ludo=E2=80=99.
