I've just run into this too. Same situation: fresh RC1 install on amd64,
libpaper1 1.1.26. United Kingdom (en_GB) locale. I expected "a4" but got
"letter" in /etc/papersize.
I notice that /var/lib/dpkg/info/libpaper1:amd64.config seems to be
missing its list of paper sizes between __BEGIN_PAPERSPECS__ and
__END_PAPERSPECS__. This might be relevant? Has the referenced
debian/rules machinery gone wrong?
defaultpaper () {
...
# Try to find a matching paper size. The data must be embedded here
# (done automatically by debian/rules) because the rest of the package
# may not have been unpacked at this stage.
...
__BEGIN_PAPERSPECS__
__END_PAPERSPECS__
}
The equivalent file on a stretch installation has contents like
__BEGIN_PAPERSPECS__
a4 210 mm 297 mm
letter 215.9 mm 279.4 mm
...
__END_PAPERSPECS__
