qtile: locale.Error: unsupported locale setting

[steveej]

Issue description

I have qtile 0.11.1 pulled in via the unstable channel at the commit seen below in the technical details section. It throws the following error on my system:

$ qtile --version
Traceback (most recent call last):
  File "/nix/store/0rhv2icj7zfbccd8wjma6m5lql5wk6ds-qtile-0.10.7/bin/..qtile-wrapped-wrapped", line 8, in <module>
    from libqtile.scripts.qtile import main
  File "/nix/store/0rhv2icj7zfbccd8wjma6m5lql5wk6ds-qtile-0.10.7/lib/python2.7/site-packages/libqtile/scripts/qtile.py", line 30, in <module>
    locale.setlocale(locale.LC_ALL, locale.getdefaultlocale())
  File "/nix/store/l9j2jsc9flrbmpf799nw9wdq59gpwms8-python-2.7.14/lib/python2.7/locale.py", line 581, in setlocale
    return _setlocale(category, locale)
locale.Error: unsupported locale setting

In my system configuration I have

  i18n = {
    consoleFont = "lat9w-16";
    defaultLocale = "en_US.UTF-8";
  };

set.

Steps to reproduce

1. set the locales as described above
2. install qtile from the unstable channel described below
3. attempt to run qtile

Technical details

• system: "x86_64-linux"
• host os: Linux 4.16.13, NixOS, 18.03.132628.a381b789984 (Impala)
• multi-user?: yes
• sandbox: yes
• version: nix-env (Nix) 2.1pre6148_a4aac7f
• channels(root): "nixos-18.03.132628.a381b789984, nixos-unstable-18.09pre140958.696c6bed4e8"
• channels(steveej): ""
• nixpkgs: /nix/var/nix/profiles/per-user/root/channels/nixos/nixpkgs

EDIT: I just noticed the above was produced with qtile 0.10.7 due to a typo in the overrides

(...)
      gitpkgs = import /home/steveej/src/github/NixOS/nixpkgs {};
(...)
    packageOverrides = pkgs: with pkgs; {
      qtile = gitpkgs.qtile;
(...)

The fork point of my local repository is currently: 9292bdb which is before the version bump of qtile which I had suspected to be the culprit.

So my actual question is, if it's not the recent version bump of qtile, what else could be breaking this?

I get a very similar error when using khard 0.12.2.

$ khard
Traceback (most recent call last):

locale.Error: unsupported locale setting

Any help would be much appreciated!

After reading #38991 (especially, this comment) I uninstalled khard from my user environment and added it to my environment.systemPackages which solved the issue for me.

I have qtile installed in environment.systemPackages and it works fine (Linux 4.16.11, NixOS, 18.09.git.0e326d3 (Jellyfish)):

$ qtile --version
0.11.1

I have qtile installed in environment.systemPackages and it works fine (Linux 4.16.11, NixOS, 18.09.git.0e326d3 (Jellyfish)):

Installing it in my systemPackages is not an option for me since I use home-manager.
I just checked after this long while and the situation is still the same:

$ qtile --version
Traceback (most recent call last):
  File "/nix/store/226yd49pimppq30yr9cx9s4wm0qcskgn-qtile-0.12.0/bin/..qtile-wrapped-wrapped", line 8, in <module>

    locale.setlocale(locale.LC_ALL, locale.getdefaultlocale())  # type: ignore

    return _setlocale(category, locale)
locale.Error: unsupported locale setting

I assume we can workaround this by exporting LOCALE_ARCHIVE as described here #38991 (comment)

Thank you for your contributions.

This has been automatically marked as stale because it has had no activity for 180 days.

If this is still important to you, we ask that you leave a comment below. Your comment can be as simple as "still important to me". This lets people see that at least one person still cares about this. Someone will have to do this at most twice a year if there is no other activity.

Here are suggestions that might help resolve this more quickly:

1. Search for maintainers and people that previously touched the related code and @ mention them in a comment.
2. Ask on the NixOS Discourse.
3. Ask on the #nixos channel on irc.freenode.net.

I'm no longer experiencing this issue.
