Use "locale -a" to show what locales your system supports at the
moment. It appears that en_US.UTF-8 is not on the list.

Installing/building additional locales is distro specific and out of
scope for this list. Please use your favorite search engine to find out
how to do it for your distro or ask in your friendly distro support forum
if necessary.

Exporting the environment variable just tells other programs what to
use. It does not help to tell them to use something that is not
installed. For bitbake you don't have to tell it anything, it insists on
using en_US.UTF-8 anyway as the error message shows.

Bitbake uses Python. To make things more confusing the locales in Python
are not necessarily named the same way as in your underlying distro and
there can be aliases.

In the end this code needs to run without returning an error

$ python
>>> import locale
>>> locale.setlocale(locale.LC_ALL, "en_US.UTF-8")
'en_US.UTF-8'

E.g. in Ubuntu the locale is listed by "locale -a" as en_US.utf8 but that
works fine.
