Why is an older version of an app getting installed here?

Help
1

I don’t understand why nix is pulling in version 1.8.0 rather than 1.8.2 of ags here. Can someone help me understand why? I’m not exactly sure what info is needed to troubleshoot further but here’s what I think is relevant:

I’m on unstable

❱ sudo nix-channel --update
unpacking channels...
❱ sudo nix-channel --list
nixos https://nixos.org/channels/nixos-unstable

(I installed nix-search using nix-shell which is why my prompt changes)

ags shows the latest version is 1.8.2

[nix-shell:~]$ nix-search ags
ags @ 1.8.2 : ags
...

But nix-shell drags down 1.8.0

[nix-shell:~]$ nix-shell -p ags

You might have an outdated user channel. What does nix-channel --list without sudo say?

3

No output, so nothing set

$ nix-channel --list
$ echo $?
0

Fascinating, anything in $NIX_PATH? Anything in ~/.config/nix?

Can you run:

nix-shell -p nix-info --command 'nix-info -m'

And paste the output, too?

5

Sure…

❱ echo $NIX_PATH
/etc/nix/path

❱ ls -l ~/.config/nix
ls: cannot access '/home/oliver/.config/nix': No such file or directory

❱ nix-shell -p nix-info --command 'nix-info -m'
 - system: `"x86_64-linux"`
 - host os: `Linux 6.6.27, NixOS, 24.05 (Uakari), 24.05.20240416.5672bc9`
 - multi-user?: `yes`
 - sandbox: `yes`
 - version: `nix-env (Nix) 2.18.2`
 - channels(root): `"nixos"`
 - nixpkgs: `/etc/nix/path/nixpkgs`

That’s overriding your channels. Where is that getting set?

I started out with the templates from nix-starter-configs/standard/nixos at main · Misterio77/nix-starter-configs · GitHub which I now see had an update a couple of months ago with a commit message of ‘add $NIX_PATH workaround’
It mentions Broken `NIX_PATH` tracking issue · Issue #9574 · NixOS/nix · GitHub

So, I’m sure you’re right. I’ll modify things later on and cross my fingers that I’m not introducing a new problem.

Thanks for your responses and useful commands :slight_smile:

Huzzah, all is working. Thanks so much for all your help.

[nix-shell:~]$ ags --version
1.8.2

I modified my version of the configuration where nixPath was being set and on a nixos-rebuild switch suddenly had 5GB of updates and some warnings about config names changing. I fixed those and all is good.
