A few new examples of installed and not installed packages from
repositories and a self build package:

[weremouse at moonstudio ~]$ apt list -qqa 'pluma'
pluma/xenial,now 1.12.2-2 amd64 [installed]

[weremouse at moonstudio ~]$ apt list -qqa 'firefox'
firefox/xenial-updates,xenial-security 62.0+build2-0ubuntu0.16.04.5 amd64
firefox/xenial 45.0.2+build1-0ubuntu1 amd64

[weremouse at moonstudio ~]$ apt list -qqa 'roxterm'
roxterm/xenial,now 3.3.2-1 amd64 [installed,automatic]

[weremouse at moonstudio ~]$ apt list -qqa 'snapd'
snapd/xenial-updates,now 2.34.2 amd64 [installed]
snapd/xenial 2.0.2 amd64


Compared with the online package search:
https://packages.ubuntu.com/xenial/snapd         snapd (2.0.2)
https://packages.ubuntu.com/xenial-updates/snapd snapd (2.34.2) 



[weremouse at moonstudio ~]$ apt list -qqa 'claws-mail'
claws-mail/xenial 3.13.2-1ubuntu1 amd64

[weremouse at moonstudio ~]$ apt list -qqa 'claws-mail-git'
claws-mail-git/now 3.17.0-1 amd64 [installed,local]


IOW if it's installed, it's marked as being installed.
