Public bug reported:
in attempting to track down why locales are unset, i noticed this issue
(perhaps related to https://bugs.debian.org/cgi-
bin/bugreport.cgi?bug=684134). running
`/var/lib/dpkg/info/locales.postinst configure` appears to unset the
seeded value of locales/locales_to_be_generated, but only if that value
was set via noninteractive means.
to reproduce (1):
# debconf-set-selections /tmp/locales.debconf (2)
# debconf-show locales
* locales/default_environment_locale: en_US.UTF-8
* locales/locales_to_be_generated: en_US.UTF-8 UTF-8
# /var/lib/dpkg/info/locales.postinst configure
Generating locales (this might take a while)...
Generation complete.
# debconf-show locales
* locales/locales_to_be_generated:
* locales/default_environment_locale: en_US.UTF-8
# cat /etc/default/locale
# File generated by update-locale
# grep -v ^\# /etc/locale.gen
[empty and locale errs continue]
on the other hand, setting the same value via an interactive `dpkg-reconfigure
locales` works:
# debconf-show locales
* locales/default_environment_locale: en_US.UTF-8
* locales/locales_to_be_generated: en_US.UTF-8 UTF-8
# dpkg-reconfigure locales (nb. en_US.UTF-8 UTF-8 is NOT pre-selected, but once
manually selected and dpkg-reconfigure has finished the locales errors are gone)
Generating locales (this might take a while)...
en_US.UTF-8... done
Generation complete.
# grep -v ^\# /etc/locale.gen
en_US.UTF-8 UTF-8
# cat /etc/default/locale
# File generated by update-locale
LANG=en_US.UTF-8
when i watch the postinst script it can be seen in an unsuccessful run that
`db_get locales/locales_to_be_generated` (line 19) gives an empty RET value:
+ db_get locales/locales_to_be_generated
+ _db_cmd GET locales/locales_to_be_generated
+ _db_internal_IFS=
+ IFS=
+ printf %s\n GET locales/locales_to_be_generated
+ IFS=
+ IFS=
read -r _db_internal_line
+ RET=
+ return 0
+ SELECTED_LOCALES=
+ echo
+ sed -e s/, /\n/g
+ SELECTED_LOCALES=
the immediately prior `db_get locales/default_environment_locale` (line
18) gives RET=en_US.UTF-8 as expected.
when locales/locales_to_be_generated has been set interactively,
RET=en_US.UTF-8 UTF-8, also as expected.
setting the value via ansible's debconf module also results in failure.
than you for your time and effort in supporting ubuntu.

1) as the locales are not configured at this point, most debconf commands
result in an additional error of:
perl: warning: Setting locale failed.
perl: warning: Please check that your locale settings:
LANGUAGE = (unset),
LC_ALL = (unset),
LANG = "en_US.UTF-8"
are supported and installed on your system.
perl: warning: Falling back to the standard locale ("C").
locale: Cannot set LC_CTYPE to default locale: No such file or directory
locale: Cannot set LC_MESSAGES to default locale: No such file or directory
locale: Cannot set LC_ALL to default locale: No such file or directory
i have left these out of this description but included them in the full
output attachment
2) see attached, generated via `debconf-get-selections` on another host
