Locales inside VE

Problem description[edit]

After creating a VE (e.g. using centos-4-i386-default template) running perl (any perl script), results in the warning message:

perl: warning: Setting locale failed.
perl: warning: Please check that your locale settings:
        LANGUAGE = "en_US:en",
        LC_ALL = (unset),
        LANG = "en_US"
    are supported and installed on your system.
perl: warning: Falling back to the standard locale ("C")

Another common problem is with PostgreSQL, if it won't start up and you see something like this in your <pgsql_data_dir>/serverlog:

invalid value for parameter "lc_messages": "en_US.UTF-8"


Some of templates have removed locales inside, since locales take really much space (~20Mb) while not needed in most cases (except for the default "C" locale).

So in this example /usr/lib/locale/en_US/LC_TIME and other files are missing.

Fix 1[edit]

reinstall glibc-common package using the command:

# rpm -ihv --force glibc-common.rpm

Fix 2[edit]

Or disable overriding of LC_* variables in /etc/ssh/sshd_config:

# Allow client to pass locale environment variables
AcceptEnv LANG LC_*


#AcceptEnv LANG LC_*

so the default LC will be used.

Fix 3[edit]

To fix this permanently for all new vzs you create, edit your /vz/templates/<distro>/<version>/<platform>/.rpmmacros and change the line %_install_langs C to include the language(s) you want, for example:

%_install_langs C:pt_PT:pt_PT.UTF-8:en_US:en_US.UTF-8

or simply

%_install_langs all

After this you will need to rebuild your OS template cache, for example:

vzpkgcache -r centos-4-i386-vmirth
vzpkgcache centos-4-i386-vmirth

Fix 4 (working on Ubuntu 8.04)[edit]

Simply install this package:

aptitude install language-pack-en-base

Fix 5 (works on Debian-like systems)[edit]

Generate the locale:

dpkg-reconfigure locales

select the one missing and generate.

Fix 6 (should work on recent Debian and Ubuntu distros)[edit]

export LANGUAGE=en_US.UTF-8
export LANG=en_US.UTF-8
export LC_ALL=en_US.UTF-8
locale-gen en_US.UTF-8
dpkg-reconfigure locales

Obviously change the en_US to your preferred language.
