Note that if you're using "lxc exec", LXD only executes the shell that
you asked for, it doesn't setup a PAM session for you, so you start with
an empty environment.

One way to solve that is to do a "su root" which will then send you
through the PAM stack (if your container has one) which will then source
any needed environment.

Another way if you don't want to go through PAM, is to set environment
variables directly on the container or one of its profiles, like:

lxc config set CONTAINER environment.LC_ALL=en_US.UTF-8

LXD will then set those environment variables for you every time you
exec a command inside the container.
