kalo  kamu menemukan error seperti ini

perl: warning: Setting locale failed.
perl: warning: Please check that your locale settings:
	LANGUAGE = (unset),
	LC_ALL = (unset),
	LANG = "en_US.utf8"
    are supported and installed on your system.
perl: warning: Falling back to the standard locale ("C").

artinya ada 2 package yg tertinggal

#aptitude install multipath-tools
#aptitude install locales

setelah selesai di install

#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


tambahkan perintah export di profile user kamu

#vim ~/.profile


masukkan line export diatas menjadi seperti ini

# cat ~/.profile
# ~/.profile: executed by Bourne-compatible login shells.

if [ "$BASH" ]; then
if [ -f ~/.bashrc ]; then
