Packages installed with dpkg -i *do* show in apt, so can you be more
specific about what you are looking for?
Yes, I am specifically trying to find packages that don't match entries
from the package lists downloaded in main, non-free, contrib, etc.
Basically, I want to identify any software that I couldn't reinstall on
a fresh install of Debian from the official Debian archives.
I forget which option it is but
apt list "~c"
or
apt list "~o"
is probably close to what you want - I think it's the second. The first
I think is for uninstalled packages that have config left behind but I
didn't make notes.
IIRC this also works:
apt list --installed | grep ,local
which I used for ages before I discovered the "~o" option. The comma is
important to filter out any packages that have local in their name, for
example:
libencode-locale-perl/stable,now 1.05-3 all [installed,automatic]
