No, it shouldn't.
Historically, DEBIAN_FRONTEND has been sent to "Noninteractive", this
has changed recently to be "noninteractive", apparently. The "correct"
way to handle this is to:
(a) not care wherever possible. if you use debconf, this should be
the case.
(b) be case insensitive where possible. this is what debconf does.
something like:
if [ "$DEBIAN_FRONTEND" ]; then
DEBIAN_FRONTEND=`echo "$DEBIAN_FRONTEND" | tr A-Z a-z`
fi
...
if [ "$DEBIAN_FRONTEND" = "noninteractive" ]; then
...
fi
(c) use the "Noninteractive" which is what debootstrap and
sbuild set
Be conservative in what you output (ie, don't change from Noninteractive to
noninteractive when it'll break packages) and liberal in what you accept
(ie, don't worry about whether it's upper or lowercase).

That is not a "fix".
