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