I’ve downloaded the latest image version 23.05 (23.05.533.c37ca420157-x86_64, to be exact)
i’m having issues installing NixOS from the installer (Calamares GUI), i’ve read the logs and it clearly states that it cannot reach cache.nixos.org/nix-cache-info if i’m not mistaken
but tried to reach that URL thru the browser on that same time and it just works and i get the 3 Line file that is located there! but the installer somehow fails to do so
Also i’ve tried other websites and they are working in order to be sure that the network config is allright
hint: I’m located in Iran, maybe that’s the problem? (e.g sanctions etc…?), because i’ve installed NixOS earlier and it just worked perfectly! (22.11) but now it doesn’t
i think the problem should be about infrastructure
Must say I would find it very disappointing if Fastly stops access to nixos.org from sanctioned regimes. I understand that they can’t do business with them. But deciding to censor a publicly accessible website is just plain unfortunate
Note that it could also very well be that Iran ISP is blocking access to fastly. Sorry I don’t want to spread FUD before we can single out the root cause.
Of course But you lose the right to complain about decisions. The most important fact is to be aware of that, and see if it complies your ethic and wallet

mirrors replaced, Nix still trying to fetch cache.nixos.org for some reason?
*edit: i’ve copied the outputs wrong, the upper message that says the operation interrupted is incorrect, i’ve fixed the URLs and updated channels successfully, it’s still trying to reach cache.nixos.org
dualstack.v2.shared.global.fastly.net is just a PTR record of cache.nixos.org from your GitHub issue. That doesn’t necessarily mean their A (ipv4) or AAAA (ipv6) record is the same. So It’s okay that you can ping one but not another. Try this instead: nc -vz cache.nixos.org 443
Delete the file (it’s a symlink to the nix store) and recreate the file with the content changed. That should allow you to configure system nix until the next NixOS rebuild
I did this, no difference, looks like it reads config from somewhere else
if i add --verbose 3 option to sudo nix-channel --update it will display error error: reading symbolic link '/nix/var/nix/profiles/per-user/root/channels/nixos-23.05': No such file or directory and exit immediately! but if i don’t use --verbose 3 it won’t display any error and continue!
why would an option specifying verbosity of output should have an effect on this?

Is there any options to completely disable cache? what is the function of a cache server? does it store the binaries of libraries, or the source code of them? As long as i know sources are all on github/gitlab or similar services.
Because of there are no ways to disable this cache thing then i think what we get is a great distro that is just unusable to a whole country (in my case Iran). I wonder if these services are also sanctioned for countries like russia, venezuela, Iraq, Syria
