=== Channel-based systems (default) === | |||
Most NixOS installations use channels by default. If you're unsure which you're using, check with `nix-channel --list`. If that returns results, you're using channels. | |||
For channel-based systems, use this configuration: | |||
{{file|/etc/nixos/configuration.nix|nix|<nowiki> | |||
system.autoUpgrade = { | |||
enable = true; | |||
flags = [ | |||
"--print-build-logs" | |||
]; | |||
dates = "02:00"; | |||
randomizedDelaySec = "45min"; | |||
allowReboot = false; # Set to true if you want automatic reboots | |||
}; | |||
</nowiki>}} | |||
<strong>Important:</strong> Do not use flake-specific flags with channel-based systems, as they will cause the upgrade to fail silently. | |||
