Re: [Nix-dev] Where to start when nixos-rebuild switch --upgrade goes wrong

[Evan Rowley]

A simple "nixos-rebuild switch --rollback" took the machine back to
16.03.836.aff03ae. Afterwards, a "nixos-rebuild switch --upgrade"
brought it to 16.03.909.f199be0. Machine is working now. Thanks to all
the nix devs who made rollback functionality work so well.

Re: [Nix-dev] Where to start when nixos-rebuild switch --upgrade goes wrong

[James Cook]

FWIW, I sometimes use git-bisect to find the first revision where
nixos-rebuild builds something with the problem. It's a huge headache,
though, due to having to reboot so many times and worrying that I
might stumble upon a revision that's more seriously broken.

I just did this to figure out why my desktop hangs after printing
"regenerating udev hardware database..." after I upgraded from 15.09
to 16.03. I'll report separately, but looks like it's the update to
systemd 225 did it.

Re: [Nix-dev] Where to start when nixos-rebuild switch --upgrade goes wrong

[zimbatm]

I usually try to look at the recent changes to find out what might gotten
wrong, both in the configuration.nix and nixpkgs. Unfortunately I don't
know of a tool that could provide that diff between two generations so I
usually stick to one change at a time.

[Nix-dev] Where to start when nixos-rebuild switch --upgrade goes wrong

[Evan Rowley]

Hi Everyone,

I performed a nixos-rebuild switch --upgrade and after rebooting, was
not able to see my usual KDE session. There was no X session. I
selected a previous generation in gummiboot and was able to have my
KDE session back. What can I do about the upgraded components which
did not work? I could issue a nixos-rebuild switch --rollback, but
would the development community benefit from finding out what went
wrong? This is a very rudimentary and unsophisticated NixOS
installation. Aside from the failed upgrade, nothing out of the
ordinairy has been done to it.

configuration.nix:

{ config, pkgs, ... }:

{
  imports =
[ # Include the results of the hardware scan.
  ./hardware-configuration.nix
];

  # Use the gummiboot efi boot loader.
  boot.loader.gummiboot.enable = true;
  boot.loader.efi.canTouchEfiVariables = true;

  networking.hostName = "ejr-e465"; # Define your hostname.
  networking.wireless.enable = true;  # Enables wireless support via
wpa_supplicant.

  # Select internationalisation properties.
  i18n = {
consoleFont = "Lat2-Terminus16";
consoleKeyMap = "us";
defaultLocale = "en_US.UTF-8";
