I've noticed that some security updates are not shown as such in the aptitude interface.
$ aptitude search "?upgradable ?archive(security)" -F "%p %t %v %V" | awk '$2~/-security/' tzdata bionic-security,bionic-updates 2018g-0ubuntu0.18.04 2018i-0ubuntu0.18.04
tzdata is listed as an available security update. However, it is not when viewed through the interface:

tzdata is listed under
Upgradable Packages instead of
Am I missing something? Not understanding how the system or the tool works?
Note: I have to filter the output of
aptitude search with
?archive(security) does not work as expected: see this related question.
