Of course it won't. The package provides /usr/lib/udev/rules.d/60-serial.rules which you should leave strictly alone for APT to handle. You would create /etc/udev/rules.d/60-serial.rules and APT will never touch that. Files under /etc/ take priority over those under /usr/lib/ when their filenames are the same. That's how both udev and systemd work. See RULES FILES under man 7 udev. Cheers, David.
