Added on Feb 13th, 2015 and marked as fix perl server

Perl is not something I have used knowingly for a long time, but of course a lot of server tools use it behind the scenes.

Just the other day I needed to quickly set up a temporary test server, but apparently I forgot something. On the command line I started seeing error messages, telling me the Perl’s locale was not set correctly:

perl: warning: Setting locale failed.
perl: warning: Please check that your locale settings:
    LANGUAGE = (unset),
    LC_ALL = (unset),
    LC_CTYPE = "nl_NL.UTF-8",
    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_ALL to default locale: No such file or directory

This is easy to fix by using locale-gen to compile a list of locale definition files:

locale-gen en_US en_US.UTF-8 nl_NL nl_NL.UTF-8

Note: in this case I also included the custom locales for nl_NL.

And then to finish it off:

dpkg-reconfigure locales
