I get the error "cannot change locale" every time on boot

Question

Error found when loading /home/weaselbee/.profile: 

Then it gives me warnings saying:

setlocale: LC_MESSAGES cannot change locale: en_US.UTF-8

LC_CTYPE: cannot change locale: en_US.UTF-8

LC_COLLATE: cannot change locale: en_US.UTF-8

Solution

To resolve this warning or install new install with local-gen data localization of default which in this case are precisely en_US.UTF8.

sudo locale-gen en_US.UTF-8 

To install / reinstall well as en_US.UTF-8 :

sudo locale-gen en en_US en_US.UTF-8

Then apply the changes with dpkg-reconfigure locales

sudo dpkg-reconfigure locales

Then

export LC_ALL="en_US"
