bug#43039: Vanilla GUIX 1.1.0 reconfigure fails on nss-certs

[Adam Griffiths]

Hey Ludo,

Thanks for getting back to me, responses are inline below.

FYI, I'm planning to format the host (Guix is inside VirtualBox) and
may not be able to assist for a period.
I literally just installed Guix into Virtual Box with the defaults,
selecting Australia / Melbourne where the option presented itself.
The only other change was enabling sshd, but regardless the issue
presents itself.
That should be enough to replicate, otherwise I'll be able to assist
further when I have my system back up.

Cheers,
Adam

I'm using en_AU

$ env | grep GUIX
GUIX_LOCPATH=/run/current-system/locale
GUIX_GTK3_PATH=/run/current-system/profile/lib/gtk-3.0
$ env | grep LC_
$

Here's my system configuration, it should be straight out of the installer.

adam@Hetzer ~$ cat /etc/config.scm

$ sudo herd status guix-daemon
Password:
Status of guix-daemon:
  It is started.
  Running value is 229.
  It is enabled.
  Provides (guix-daemon).
  Requires (user-processes).
  Conflicts with ().
  Will be respawned.
$ sudo cat /proc/229/environ | tr '\0' '\n'

LC_ALL=en_US.utf8

Shouldn't this be en_AU.utf8? Or at least en_GB.utf8?

There is an en_AU locale available:
$ ls /run/current-system/locale/2.29/en_AU.utf8/LC_MESSAGES/
SYS_LC_MESSAGES

I notice there's also 2 en_US locales:

$ /run/current-system/locale/2.29/en_US.
en_US.utf8/  en_US.UTF-8/

The locales all _appear_ to be there

$ ls /run/current-system/locale/2.29/en_*/
/run/current-system/locale/2.29/en_AU.utf8/:
LC_ADDRESS  LC_CTYPE           LC_MEASUREMENT  LC_MONETARY  LC_NUMERIC

But the contents of the LC_MESSAGES directories differ.

Is this correct?
At first glance (with no knowledge of how the locales work) I would
assume that en_AU and en_CA overlay onto en_GB.
But even en_GB is effectively empty, which would contradict that assumption.
