This confuses me, because the config script does the following:
while [ -z "$MIRRORSITE" ] ; do
db_input high pbuilder/nomirror || true
db_input high pbuilder/mirrorsite && RETCODE=$? || RETCODE=$?
db_go
# if the interface is non-interactive, still set a valid mirror
if [ $RETCODE = 30 ] ; then
MIRRORSITE="http://deb.debian.org/debian";
else
db_get pbuilder/mirrorsite
MIRRORSITE="$RET"
fi
done
So it’s supposed to be detecting the non-interactive case (and 30 is
the documented value for that), providing a default. Yes, we should do
better in the deb822 cases (note that the script *does* check
sources.list.d, but only for *.list, which are in the same format as
sources.list itself), and maybe there’s a way we can extract that
information out of apt itself (e.g. something like apt-cache policy
dpkg, but not quite), but the above code should still be making that
matter less. I’ll have to go test this myself, see if I can reproduce
it, and figure out why it’s not working.
