[How to do instruction] Error when login as pi

[UpsiUps]

Hi,

when you currently login outside of GB into the pi account you will get an error like this:
-bash: warning: setlocale: LC_ALL: cannot change locale (de_DE.UTF-8)
to get rid of this error do the following steps:

sudo vi /etc/locale.gen

Search your locale setting ( e.g. de_DE.UTF-8)  and un-comment that line (delete the '#' ) and save the file ( you could keep en_GB.UTF-8)
then let your locales generate by :
sudo locale-gen

you will see something like:
Generating locales (this might take a while)...
  de_DE.UTF-8... done
  en_GB.UTF-8... done
Generation complete.
