Last week i was trying to make my Raspberry Pi work again, and while reinstalling and upgrading Raspbian OS packages i run into an issue where a perl warning is displayed.
The warning message apprears during the installation packages(invoking Perl) and it's due to missing locales being set not :
[...] perl: warning: Setting locale failed. perl: warning: Please check that your locale settings: LANGUAGE = (unset), LC_ALL = (unset), LC_TIME = "fr_FR.UTF-8", LC_MONETARY = "fr_FR.UTF-8", LC_ADDRESS = "fr_FR.UTF-8", LC_TELEPHONE = "fr_FR.UTF-8", LC_NAME = "fr_FR.UTF-8", LC_MEASUREMENT = "fr_FR.UTF-8", LC_IDENTIFICATION = "fr_FR.UTF-8", LC_NUMERIC = "fr_FR.UTF-8", LC_PAPER = "fr_FR.UTF-8", LANG = "en_GB.UTF-8" are supported and installed on your system. perl: warning: Falling back to the standard locale ("C"). locale: Cannot set LC_ALL to default locale: No such file or directory
You can fix the issue by setting the locale to en_US.UTF-8 for example:
$ 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
Once you run the last command a dialog will appear to let you choose the desired locale.
