warning: failed to install locale

warning: failed to install locale

Hi!

I've installed Guix on a foreign distro (Debian 9) using the shell
installer script [1] linked in "Binary Installation" (and skipped
"manual verification" of each step)

I've also followed "Application setup", in particular for locales:

--8<---------------cut here---------------start------------->8---
$ guix package -I
nss-certs	3.39	out	/gnu/store/xbj4fhad0lnz0ziflwi90gyqbls8ains-nss-certs-3.39
glibc-utf8-locales	2.28	out	/gnu/store/94k5w17z54w25lgp90czdqfv9m4hwzhq-glibc-utf8-locales-2.28
--8<---------------cut here---------------end--------------->8---

and

--8<---------------cut here---------------start------------->8---
(anemone)g@anemone:~$ echo $GUIX_LOCPATH
/localhome/g/.guix-profile/lib/locale
--8<---------------cut here---------------end--------------->8---

but every time I try to run "guix build" I get the following message:

--8<---------------cut here---------------start------------->8---
$ guix build emacs --dry-run

am I doing something wrong?

[1] slightly hacked since I'm using a /gnu directory previuosly created
on LVM and mounted via fstab, we should consider this sort of use-cases
(I'll propose a patch later this week)

Re: warning: failed to install locale

Dear,

If you are doing something wrong, I am doing the same. ;-)

I have the same issue on foreign distro, also Debian.
The hint fixes the warning for "regular" commands.
But the warning seems remaining when substitute is called. Any clue?


All the best,

This tells us that environment within the context of the “substitute”
executable is not correct.  You need to make sure that the daemon’s
environment is correct, i.e. that GUIX_LOCPATH points to a profile that
contains a glibc-utf8-locales package that matches the version of the
glibc that’s in use for the daemon.

Dear Ricardo,

Thank you for the explanations.

Maybe I am doing wrong.

$ ldd /var/guix/profiles/per-user/root/current-guix/bin/guix-daemon
[...]
libc.so.6 => /gnu/store/h90vnqw0nwd0hhm1l5dgxsdrigddfmq4-glibc-2.28/lib/libc.so.6


So the version is 2.28, right?
Then my profile contains the version 2.28 of the locale, I guess.

$ echo $GUIX_LOCPATH
/home/simon/.guix-profile/lib/locale
$ ls `echo $GUIX_LOCPATH`
2.28

Is not correct?

I also tried to restart the daemon, in case. :-)
Because the machine should be turned on with the daemon linked to one
glibc. Then `guix pull' and `guix package -i glibc-locales' does not
necessary install the correct version, I guess.
I mean, does `guix pull' restart the daemon?


All the best,
simon

This is in your environment.  But what about the daemon’s environment?
It is not started in your environment where GUIX_LOCPATH is set.  How do
you start the daemon?  If it’s via systemd you may want to look at the
service file to see where GUIX_LOCPATH points.

No, it only installs a new version of Guix in $HOME/.config/guix/

Thank you.
I got it.

Now, it is clear. :-)

Thank you for this straightforward answer Ricardo. I post some insights
below.

In fact:
echo $GUIX_LOCPATH
gives no output as root (which runs the Guix daemon, presumably).

Where is the service file supposed to be and how to include GUIX_LOCPATH
in it?

I also ran the script to install Guix. Perhaps this script should do all
the setup.

I had the same problem, which was solved by installing glibc-utf8-locales
in root's profile and adding the export line to root's ~/.profile, which
fits Ricardo's explanations.

Re: warning: failed to install locale

[zimoun]

Dear,


> echo $GUIX_LOCPATH
> gives no output as root (which runs the Guix daemon, presumably).

If I understand well, this should be expected. :-)

The $GUIX_LOCPATH in the root `env' is not necessary related to the
$GUIX_LOCPATH is the daemon `env'.


Well, if you run systemd, then the variable is defined in, say:

grep GUIX_LOCPATH /etc/systemd/system/guix-daemon.service

There you see where the GUIX_LOCPATH used by the daemon points to.
By default, the profile should be:
/var/guix/profiles/per-user/root/guix-profile/lib/locale

Therefore, if you install as root the glibc-utf8-locales, then it
should work. As Edouard said.

However, note that glibc-utf8-locales only contains the locales:
("de_DE" "el_GR" "en_US" "fr_FR" "tr_TR")

If the daemon is configured with another locale, then the simplest is
to install glibc-locales.
If your bandwidth is limited, be patient ;-) Or build a variant of
glibc-ut8-locales with your required locale.


If you run Upstart, it should be similar.

Hope that help.


All the best,
simon

OK now I understand too, thanks!

yes, Debian starts daemons via systemd and this issue is easily fixed by
installing glibc-utf8-locales in the guix default root profile:

  sudo -i
  guix package -i glibc-utf8-locales
  sudo systemctl restart guix-daemon.service

after doing so, when I "guix build emacs --dry-run" the warning I
reported disappeared

I think a similar approach should resolve similar issues with other init
systems

since I used the binary install script [1] I think we should easily
patch that so that it also "guix package -i glibc-utf8-locales" for lazy
users like me :-)

I'm going to test the binary install script on a brend new Debian 9 lxc
container since I found other possible improvements

this is also not clearly stated in
https://www.gnu.org/software/guix/manual/en/html_node/Application-Setup.html#Locales-1
do it need to be fixed?

AFAIU adding "export GUIX_LOCPATH=$HOME/.guix-profile/lib/locale" to
root's .profile or .bash_profile is not strictly needed (unless you want
to install and run packages as root user), so I'd _not_ automate this
via the binary install script or document this

Thanks!
Giovanni

It should be: "guix package -i glibc-locales".
Because glibc-utf8-locales only contains the locales ("de_DE" "el_GR"
"en_US" "fr_FR" "tr_TR"). If I understand well.

To patch correctly, the locale should be guessed by the script and the
variant glibc-LOC-locales should be built on-the-fly and installed.
It is some work and I am not sure it will pay off. :-)

From my opinion, yes. :-)
