How-to fix "Warning: No support for locale: en_US.utf"

locale.sh

This is because locale-gen is using an archive file to store all the locales, but many utilities are still looking for the locale files.

Have a look at /usr/lib/locale/. If your output looks like this, read on:

ls /usr/lib/locale/

C.UTF-8  locale-archive


The warning isn't critical, as far as I can tell, but if it bothers you or causes troubles, try the following in a terminal window:

sudo locale-gen --purge --no-archive


This command purges (deletes) the archive file and replaces it with the .utf8 files.

ls /usr/lib/locale/

C.UTF-8     de_LI.utf8  en_CA.utf8  en_IN       en_US.utf8
de_AT.utf8  de_LU.utf8  en_DK.utf8  en_NG       en_ZA.utf8
de_BE.utf8  en_AG       en_GB.utf8  en_NZ.utf8  en_ZM
de_CH.utf8  en_AU.utf8  en_HK.utf8  en_PH.utf8  en_ZW.utf8
de_DE.utf8  en_BW.utf8  en_IE.utf8  en_SG.utf8



sudo dpkg-reconfigure locales

sudo update-locale LANG=en_US.UTF-8

Edit /etc/environment
Add:
LC_ALL=en_US.UTF-8
LANG=en_US.UTF-8
