Bug#854463: FTBFS without user input with a controlling TTY

[James Clarke]

Source: kodi
Version: 2:17.0~rc3+dfsg1-2
Severity: serious

In a freshly-unpacked source directory, dpkg-buildpackage (or pdebuild,
or sbuild) blocks in the clean target trying to reverse some patches,
because they were never applied (they get applied during configure) and
patch prompts the user for input. The user needs to answer 44 questions
before the clean target actually finishes:

> ls /«BUILDDIR»/kodi-17.0~rc3+dfsg1/debian/patches/libdvdnav-* | tac | xargs cat | patch -R --no-backup-if-mismatch -r - -s -p1 \
