I did get the same result (pbuilder artful clean environment) I also did try to reproduce autopkgtestsuite in an lxc container and the test has failed
sudo autopkgtest-build-lxc ubuntu artful autopkgtest --shell-fail --apt-upgrade screen_4.5.1-3ubuntu1.dsc -- lxc --sudo autopkgtest-artful
the problem is that when the test fails, you get a shell inside the container, and prove -v debian/tests/t works there :( culprit might be that screen -X and screen -Q stopped working
