Rebuild

Then generate the missing locale and reconfigure locales to take notice:

$ sudo locale-gen "en_US.UTF-8"
Generating locales...
  en_US.UTF-8... done
Generation complete.

Ask a bunch of questions, but skip and continue:

$ sudo dpkg-reconfigure locales
Generating locales...
  en_US.UTF-8... up-to-date
Generation complete.
