This does not generally work as far as I know. You have to hardcode the domain name there (or use cdbs' langpack.mk which adds the field for you). However, the domain name shouldn't change, so if you just hardcode it it should be just fine.

That's explained in https:/ /wiki.ubuntu. com/Interactive UpgradeHooks : ship it in /usr/share/ packagename and have the postinst copy it to /var/lib/ update- notifier/ user.d/ .
