The Debian packaging is now hosted on Debian servers at
git://git.debian.org/users/stapelberg/i3lock.git

This makes life easier for Debian people. It makes life harder
for you if you want to build a Debian package of the current
git version. Here is how you could do that now:

Build a tarball of the current git version:
mkdir ../i3lock-dpkg
VERSION=i3lock-$(git describe --tags)
git archive --prefix=$VERSION/ --output=../i3lock-dpkg/$VERSION.tar.bz2 HEAD

get the packaging:
cd ../i3lock-dpkg
gbp-clone git://git.debian.org/users/stapelberg/i3lock.git
cd i3lock
git-import-orig ../$VERSION.tar.bz2
dpkg-buildpackage
