Dear maintainers, I badly got bitten by this bug, too, while trying to (automatically) install Debian Jessie (stable) with FAI.
When installing locales and then reconfiguring it with # dpkg-reconfigure locales it works as expected using dialog input method. Trying to reconfigure locales noninteractively, it fails: # echo "set locales/locales_to_be_generated de_DE.UTF-8 UTF-8" | chroot $NFSROOT debconf-communicate perl: warning: Setting locale failed. perl: warning: Please check that your locale settings: LANGUAGE = (unset), LC_ALL = (unset), LANG = "de_DE.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 0 value set # echo "set locales/default_environment_locale de_DE.UTF-8" | chroot $NFSROOT debconf-communicate perl: warning: Setting locale failed. perl: warning: Please check that your locale settings: LANGUAGE = (unset), LC_ALL = (unset), LANG = "de_DE.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 0 value set # chroot $NFSROOT dpkg-reconfigure -fnoninteractive locales perl: warning: Setting locale failed. perl: warning: Please check that your locale settings: LANGUAGE = (unset), LC_ALL = (unset), LANG = "de_DE.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 Workaround (thanks to Thomas Lange from FAI): Don't install locales with all the other packages but seperately (e. g. with a script). Configure locales before installation. Do not reconfigure them (noninteractively). https://lists.uni-koeln.de/pipermail/linux-fai/2015-May/thread.html#10890 https://lists.uni-koeln.de/pipermail/linux-fai/2015-May/010922.html Thanks for attention.
