E changelog-file-missing-in-native-package

Each Debian package (which provides a /usr/share/doc/pkg directory) has to install a changelog file. Since this package seems to be a native Debian package (i.e., there is no upstream source), the file should usually be installed as /usr/share/doc/pkg/changelog.gz

Note that Lintian may emit this tag if the changelog exists, but it does not look like a Debian changelog.

Refer to Debian Policy Manual section 12.7 (Changelog files and release notes) for details.
