dpkg warning while updating kali dir

Updating kali dir and im getting this warning returned in the middle of doing the full-upgrade through cmd ...

Code:

---

Setting up dpkg (1.21.7kali1) ...
dpkg: warning: This system uses merged-usr-via-aliased-dirs, going behind dpkg's back, breaking its core assumptions.
dpkg: warning:This can cause silent file overwrites and disappearances, and its general tools misbehavior.
dpkg: warning: dpkg-db-backup.service is a disabled or a static unit not running, not starting it.

Just wondering if someone knows the work around for this. I'd rather ask and get input of someone more knowledgeable than myself here so I don't risk breaking the system further. Thanks in advance!
