I'm getting this message when running apt-get:

perl: warning: Setting locale failed.
perl: warning: Please check that your locale settings:
LANGUAGE = (unset),
LC_ALL = (unset),
LC_COLLATE = "en_US",
LC_TYPE = "en_US",
LC_MESSAGES = "en_US",
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_MESSAGES to default locale: No such file or directory
locale: Cannot set LC_ALL to default locale: No such file or directory

My /etc/default/locale file contains this:

# File generated by update-locale
LANG="en_US.UTF-8"
LC_TYPE="en_US"
LC_MESSAGES="en_US"
LC_COLLATE="en_US"

/var/lib/locales/supported.d/en contains this:

en_HK.UTF-8 UTF-8
en_DK.UTF-8 UTF-8
en_IN UTF-8
en_ZW.UTF-8 UTF-8
en_NZ.UTF-8 UTF-8
en_PH.UTF-8 UTF-8
en_NG UTF-8
en_US.UTF-8 UTF-8
en_GB.UTF-8 UTF-8

en_SG.UTF-8 UTF-8
en_BW.UTF-8 UTF-8
en_AG UTF-8
en_ZA.UTF-8 UTF-8
en_CA.UTF-8 UTF-8
en_IE.UTF-8 UTF-8

...and /var/lib/locales/supported.d/local contains this:

en_US.UTF-8 UTF-8

What am I missing here?

Thanks, Len

Looks like the "C" locale isn't installed on your system? You can check with locale -a. Doing export LC_ALL="en_US" before running apt-get may help (or may not).

I ran into something this with a fresh squeeze deployment. Check the setting of AcceptEnv in sshd_config -- in my case, it was caused by exporting Dutch environment variables to an English-only server.

An attempt to export LC_ALL="en_US", resulted in:

-bash: warning: setlocale: LC_ALL: cannot change locale (en_US): No such file or directory

...and sshd_config contains:

AcceptEnv LANG LC_*

Thanks, Len

The locales for your region might not be installed. Try "apt-get install language-pack-en" (if using Ubuntu, at least)... that might get the things rolling.

Comment it out, i.e. stop the export of environment variables from your workstation to your server.

apt-get says the English language pack is already installed.

Commenting out the export in sshd_config had no effect, the same errors/warnings are showing up.
