[SOLVED] LC_CTYPE: cannot change locale (UTF-8): No such file or directory

I was trying to SSH my CentOS 6.5 and i got this error:
-bash: warning: setlocale: LC_CTYPE: cannot change locale (UTF-8): No such file or directory
then i directly goto that system and run update command and got this error:
Error: Cannot retrieve metalink for repository: epel. Please verify its path and try again

I tried so many commands, but non of them works for me, finally i got this solution and guess what it’s works!
Open “/etc/environment” file and add two lines given below. Thats it!

# vi /etc/environment

LANG=en_US.utf-8
LC_ALL=en_US.utf-8

Save and exit from file, now try to connect via SSH or use “yum update” command. I hope it will work for you also.
