"locales is broken or not fully installed" problem

[davboc]

Hi all!

I have a Rpi2 with Raspbian. I use it only via command line. Actually I have a problem with locale, I post the output of some commands:

pi@raspberrypi ~ $ locale
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
LANG=en_GB.UTF-8
LANGUAGE=
LC_CTYPE="en_GB.UTF-8"
LC_NUMERIC="en_GB.UTF-8"
LC_TIME="en_GB.UTF-8"
LC_COLLATE="en_GB.UTF-8"
LC_MONETARY="en_GB.UTF-8"
LC_MESSAGES="en_GB.UTF-8"
LC_PAPER="en_GB.UTF-8"
LC_NAME="en_GB.UTF-8"
LC_ADDRESS="en_GB.UTF-8"
LC_TELEPHONE="en_GB.UTF-8"
LC_MEASUREMENT="en_GB.UTF-8"
LC_IDENTIFICATION="en_GB.UTF-8"
LC_ALL=


pi@raspberrypi ~ $ locale -a

and if I launch "sudo raspi-config" and choose the "Internationalisation Options" then "change locale" I get this error:
"There was an error running option I1 Change Locale" and this is the output:

sudo raspi-config

I don't know what can I do, I suppose that the problem could be in the /etc/apt/sources.list

deb http://mirrordirector.raspbian.org/raspbian/ wheezy main contrib non-free rpi
deb http://archive.mene.za.net/raspbian wheezy contrib

but I don't know how I can change it.

Please help me!

Thank you all!

I solved changing wheezy to jessie in the first line of /etc/apt/sources.list:

deb http://mirrordirector.raspbian.org/raspbian/ jessie main contrib non-free rpi
deb http://archive.mene.za.net/raspbian wheezy contrib

Now I don't know if is better leave it, change both to jessie or restore both to wheezy.

I'm waiting for your help

I consulted your process and solved my problem, thanks.The difference between us is that I have fixed LC_ALL = (unset) in advance.
1)Open this file(/etc/default/locale).
2)Append or modify as this(LANG=zh_CN.UTF-8 LANGUAGE=zh_CN:zh:en_US:en LC_ALL=zh_CN.UTF-8)
I hope I can help you, thank you.
