I encountered an error during on Debian using LXC containers, it did not appear to break anything, so other than being annoying there was no reason to actively fix this. The error stated:

perl: warning: Setting locale failed.
perl: warning: Please check that your locale settings:
LANGUAGE = "en_US:en",
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
debconf: delaying package configuration, since apt-utils is not installed

Fix it by entering:

echo "en_US.UTF-8 UTF-8" > /etc/locale.gen
apt-get -y --force-yes install locales
dpkg-reconfigure locales

In dpkg-reconfigure, select the correct locale (mine is 'en_US.UTF-8')
