#260805 — apt policy / listing packages from repo

There seems to be no mention of 

apt policy

in either man apt or apt --help.

I was looking for a way to list packages installed from a particular repo and/or sub-repo or whatever it's called (eg. main, non-free).

Does anyone know of a way to do this, with apt policy or otherwise?

Thanks,
Gareth

As   man apt   says:

 "Much like apt itself, its manpage is intended as an end user
  interface and as such only mentions the most used commands and
  options partly to not duplicate information in multiple places
  and partly to avoid overwhelming readers with a cornucopia of
  options and details."

What I do in this situation is to type "apt" and press TAB twice.
Look at the resulting list of commands and check the man page for
the most likely looking, in this case apt-cache.

An alternative method of course is to type   apt policy   into any
search engine. This will typically tell you not only how to invoke
the command, but also more about what it produces.

As for your listing, I've done this in the past with a script that
runs apt-cache dump, grepping the Package/Version/File lines,
concatenating and sorting them, then filtering that list against
the output of dpkg-query -W -f to include only installed packages.
This yields a list like:

  Package: acl Version: 2.2.53-10 File: /var/lib/apt/lists/deb.debian.org_debian_dists_bullseye_main_binary-amd64_Packages
  Package: adduser Version: 3.118 File: /var/lib/apt/lists/deb.debian.org_debian_dists_bullseye_main_binary-amd64_Packages
  [ … … ]
  Package: xtoolwait Version: 1.3-6.2 File: /var/lib/dpkg/status
  [ … … ]
  Package: yt-dlp Version: 2023.03.04-1~bpo11+1 File: /var/lib/dpkg/status

which you can grep for particular subsets, though I'm usually more
interested in grep -v for packages originating from elsewhere,
like xtoolwait (squeeze) and yt-dlp (backports) there.

There may well be better ways.

Cheers,
David.

I would probably use "apt list" with a search pattern described in
apt-patterns(7), e.g. the following command lists all installed packages
from non-free:

$ apt list '~i ~snon-free/'

Lots of interesting possibilities one can toy with. :-)

Cheers,
       Sven

I will look into both approaches - my thanks to you and David.
