Each Debian package (which provides a /usr/share/doc/pkg directory) must install a Debian changelog file in /usr/share/doc/pkg/changelog.Debian.gz
A common error is to name the Debian changelog like an upstream changelog (/usr/share/doc/pkg/changelog.gz); therefore, > Lintian will apply further checks to such a file if it exists even after issuing this error.
Refer to Debian Policy Manual section 12.7 (Changelog files and release notes) for details.
The Debian Policy Manual says:
Packages that are not Debian-native must contain a compressed copy of the debian/changelog file from the Debian source tree in /usr/share/doc/package with the name changelog.Debian.gz.
If an upstream release notes file is available, containing a summary of changes between upstream releases intended for end users of the package and often called NEWS, it should be accessible as /usr/share/doc/package/NEWS.gz. An older practice of installing the upstream release notes as /usr/share/doc/package/changelog.gz is permitted but deprecated.
