Yes, this bug report is invalid. You have the Ubuntu 14.04 version of dpkg installed and are trying to install glibc from 18.04. And somehow apport reports that the version of your system is Ubuntu 16.04. You need to properly upgrade to Ubuntu 16.04 (which absolutely must include dpkg!) before upgrading to Ubuntu 18.04.
