My autoUpgrade is failing with the error message
.../nixos-rebuild: unknown option `-I'
I see from that this issue has been fixed in commit 6dcfaeb32 in the GitHub repo of nixpkgs. How do I upgrade my system to that version?
Here are some of my settings:
$ sudo nix-channel --list
[sudo] password for ...
nixos https://channels.nixos.org/nixos-unstable
$ cat /etc/nixos/configuration.nix
...
system.autoUpgrade.enable = true;
system.autoUpgrade.allowReboot = true;
system.autoUpgrade.channel = "https://channels.nixos.org/nixos-unstable";
...
Thank you.
