You could use check-dfsg-status.
check DFSG compliance of installed packages
This program will analyze the set of currently-installed packages on a
Debian-based system, and report all of the packages from the non-free and
contrib trees which are currently installed.
.
Note that check-dfsg-status is not limited to Debian systems only (which
means that it also works with Debian-derived distributions such as Ubuntu).
It is also not limited to Linux-based systems.
.
This program was originally called vrms but as the opinions of Richard M.
Stallman and the Debian project have diverged since the program was written
it has been renamed to check-dfsg-status. This is also a more accurate name
as the program always followed the Debian Free Software Guidelines.
