Each package must contain a file named "copyright" which contains the
license(s) which apply to that package.
On an installed system, these are in the /usr/share/doc/PKGNAME/
directories:
unicorn:~$ ls /usr/share/doc/libc6
changelog.Debian.gz copyright NEWS.gz README.hesiod.gz
changelog.gz NEWS.Debian.gz README.Debian.gz

Therefore, I would like to ask, when the two documents "license.txt" and "Copyleft" exist in the software package at the same time, which one should the user take as the basis, and how to deal with the situation where the declared license information of the two documents is inconsistent, Which shall prevail?
The term "copyleft" is used by GNU (specifically Richard Stallman, I
believe) to describe the GNU General Public License (GPL). I've never
seen that term used in any other context. It's certainly not the name
of any file present in Debian packages at large.

Again, the license(s) are in the "copyright" files, one per package.
