When I boot pi it it throws the following warnings:

-bash: warning: setlocale: LC_ALL: cannot change locale (en_US.UTF-8)
-bash: warning: setlocale: LC_ALL: cannot change locale (en_US.UTF-8)
->bash: warning: setlocale: LC_ALL: cannot change locale (en_US.UTF-8)

When I do 

>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_US LANGUAGE=en_US LC_CTYPE="en_US.UTF-8" LC_NUMERIC="en_US.UTF-8" LC_TIME="en_US.UTF-8" LC_COLLATE="en_US.UTF-8" LC_MONETARY="en_US.UTF-8" LC_MESSAGES="en_US.UTF-8" LC_PAPER="en_US.UTF-8" LC_NAME="en_US.UTF-8" LC_ADDRESS="en_US.UTF-8" LC_TELEPHONE="en_US.UTF-8" LC_MEASUREMENT="en_US.UTF-8" LC_IDENTIFICATION="en_US.UTF-8" LC_ALL=en_US.UTF-8

I changed the contents of /etc/default/locale to the following

# File generated by update-locale LANG=en_US.UTF-8 LANGUAGE=en_US:en LC_ALL=en_US.UTF-8

I tried to reconfigure locale using

sudo dpkg-reconfigure locales

But every time the menu opens, with no selection made. I have to select

en_US.UTF-8 UTF-8

every time.And selecting this throws the error

Generating locales (this might take a while)...
Generation complete.
*** update-locale: Error: invalid locale settings: LANG=en_GB.UTF-8 LANGUAGE="en_US.UTF-8" LC_ALL="en_US.UTF-8"

How do I remove these warnings?

    Have you used raspi-config to setup International options? Commented Mar 4, 2016 at 10:51

    yes I did that but to no avail. I had wheezy when this problem was there. Now I have installed Jessie, still this persists. I don't know how after formatting the card and installing a new os this problem can still be there. Commented Mar 14, 2016 at 17:39
  • This worked for me... daker.me/2014/10/… Good luck!!! Commented Feb 12, 2018 at 9:13

This blog post helped me: Raspberry Pi -- Fixing your Locale http://www.jaredwolff.com/blog/raspberry-pi-setting-your-locale

  • Edit /etc/locale.gen and uncomment the line with en_US.UTF-8 e.g. sudo nano /etc/locale.gen
    uncomment line by deleting leading #

  • Run sudo locale-gen en_US.UTF-8

  • Run sudo update-locale en_US.UTF-8

The other answers weren't working for me but I found one that did.

Run sudo nano /etc/default/locale

Change it to include these three lines:

LANG=en_US.UTF-8 LC_ALL=en_US.UTF-8 LANGUAGE=en_US.UTF-8

Then reboot the system and it should be updated.

    This is what worked for me after creating images using rpi-imager. The original Noobs created image was ok. Commented Aug 13, 2023 at 17:59
  • I can confirm that this worked also after creating the image using rpi-imager. Also, if I change the locale after setting it to en_US.UTF-8 the contents of /etc/default/locale don't seem to be changed totally: I needed to re-edit LC_ALL and LANGUAGE to match the new default locale.

Edit your /etc/locale.gen then uncomment the following line:

en_GB.UTF-8 UTF-8

Run:

sudo locale-gen en_GB.UTF-8 UTF-8 sudo update-locale en_GB.UTF-8 UTF-8 export LANGUAGE=en_GB.UTF-8 export LC_ALL=en_GB.UTF-8

Verify it;

locale

You may get:

LANG=en_GB.UTF-8 LANGUAGE=en_GB.UTF-8 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=en_GB.UTF-8

And Done !!!

Since you flashed a new image and it continues to not work, it sounds like you might have a hardware issue. Do you have another raspberry pi to try it on? If you do and you get the same error, make sure you are downloading the right image or try noobs to make sure. If you do not have another raspberry pi, I recommend running sudo update-locale en_US.UTF-8 and seeing if that fixes the issue.
