Your dpkg log shows you are upgrading:
apt:amd64 (1.0.1ubuntu2.24, 1.6.12)
update-notifier-common:amd64 (0.154.1, 3.192.1.7)
So somehow you were attempting to do an upgrade directly from Ubuntu
14.04 to Ubuntu 18.04, which is not supported.

Hello,
Here comes the output of 'apt-cache policy update-notifier-common':
update-notifier-common:
Installed: 3.168.10
Candidate: 3.168.10
Version table:
*** 3.168.10 500
500 http://br.archive.ubuntu.com/ubuntu xenial-updates/main amd64
Packages
500
Note that update-notifier-common which has this versioned pre-dependency
on apt is only in 18.04, and apt in 16.04 is at version 1.2.10ubuntu1.
So this problem should never affect a supported upgrade from
14.04->16.04->18.04.
