About libjack-jackd2-0 and other dependencies

Sorry for my out-dated question.

First, I really appreciate sam to keeping update this old device until this summer.
I’m trying to install pulseaudio and dependencies using build-dep command.
aptitude is suggesting me to remove libjack-jackd2-0.
On my googling, I aware that libjack-jackd2-0 is installed with kodi 16, and I’m using that build.
Should I keep this package safe?

and also, aptitude is trying upgrade libpam-systemd, systemd, systemd-sysv, udev [215-17+deb8u6 (now) -> 215-17+deb8u7 (oldstable)].
Could this break the build(atv-osmc January.2017)?

please ignore this question.
I aborted jackd2-0 erase and upgraded others.
That made no issue in my case.
