Nixpkgs: nixos-unstable channel vanished

[ericsagnes]

Issue description

There is no nixos-unstable channel in http://nixos.org/channels/ anymore.

[Mic92]

still a problem? I saw: "nixpkgs-unstable/ 2016-09-23 18:45 - "
UPDATE Sorry, I misread the name: nixos-unstable is indeed gone

Is nixpkgs different from nixos?
Edit: *Isn't

[ericsagnes]

Is nixpkgs different from nixos?

Yes it is, nixos include tests and nixpkgs includes some darwin builds.

• nixos-* channels expression: https://github.com/NixOS/nixpkgs/blob/master/nixos/release-combined.nix
• nixpkgs-* channels expression: https://github.com/NixOS/nixpkgs/blob/master/pkgs/top-level/release.nix

It seems that the _channel symlink_ to the latest unstable release is gone, it also seems that the actual unstable release that was created at 2016-09-23 is gone from the release folder, can only see an earlier release that was created at 2016-09-21.

Also seeing a deadlock error on hydra for trunk-combined:

DBIx::Class::Storage::DBI::_dbh_execute(): DBI Exception: DBD::Pg::st execute failed: ERROR:  deadlock detected
DETAIL:  Process 19543 waits for ShareLock on transaction 20589107; blocked by process 10826.
Process 10826 waits for ShareLock on transaction 20589096; blocked by process 19543.
HINT:  See server log for query details.

Maybe the latest release was removed accidentally and the channel symlink couldn't be created?

The issue still persists. Are there any news?

The same issue:
nixos-rebuild switch --upgrade results in error:
unable to download ‘https://nixos.org/channels/nixos-unstable/nixexprs.tar.bz2’:

Is there any hope this to be fixed soon?

The same issue:
nixos-rebuild switch --upgrade results in error:
unable to download
‘https://nixos.org/channels/nixos-unstable/nixexprs.tar.bz2’:

same issue here. This blocks any nixos upgrade on unstable channel.

[edolstra]

Should work again.

[yacinehmito]

It does. Thank you very much!

still broken (at least in webUI) for 16.03 and unstable
https://nixos.org/channels/

I get "nix-channel compatibility placeholder" and link to https://d3g5gsiof5omrk.cloudfront.net/nixos/unstable/nixos-17.03pre92039.adfcc2d for unstable channel

Well, nix-channel --update seems to work fine on those placeholders.

I have system.autoUpgrade running nightly, yet my nixos-version seems to have been stuck at adfcc2d9531e78bf6a9e3b56e2f4fc873cb3d87b for multiple weeks. Does system.autoUpgrade do something different from nix-channel --update such that it wouldn't update?

(Edit: I've repeatedly run nixos-rebuild switch in that time, so I wouldn't think that the lack of updates is caused by errors in my NixOS configuration.)

[vcunat]

@8573: that _is_ the latest nixos-unstable, unfortunately.
