debian packaging - wrong debian changelog package name

[prahal]

The debian/changelog in the develop branch has NixNote as package name.
But Debian only allow lowercase in the package name.
Also, the package name in the debian/changelog has to match the one in the debian/control file (which is nixnote2).

LC_ALL=C dpkg-buildpackage -rfakeroot -b -us -uc -j4
dpkg-buildpackage: info: source package NixNote
dpkg-buildpackage: info: source version 2.1.10
dpkg-buildpackage: info: source distribution stable
dpkg-buildpackage: info: source changed by Robert Spiegel <nightingale7@gmail.com>
dpkg-buildpackage: info: host architecture amd64
 dpkg-source --before-build .
dpkg-source: error: source package name 'NixNote' is illegal: character 'N' not allowed
dpkg-buildpackage: error: dpkg-source --before-build . subprocess returned exit status 255

once I lowercase to nixnote the package name in the changelog I get:

LC_ALL=C dpkg-buildpackage -rfakeroot -b -us -uc -j4
dpkg-buildpackage: info: source package nixnote
dpkg-buildpackage: info: source version 2.1.10
dpkg-buildpackage: info: source distribution stable
dpkg-buildpackage: info: source changed by Robert Spiegel <nightingale7@gmail.com>
dpkg-buildpackage: info: host architecture amd64
 dpkg-source --before-build .
dpkg-source: error: source package has two conflicting values - nixnote2 and nixnote
dpkg-buildpackage: error: dpkg-source --before-build . subprocess returned exit status 255

I don't know the policy to migrate a package to a new name. I noticed that it could be via a transitional empty package with the old name that depends on the new name. I believe you also have to add conflicts/replaces to the new package control file to replace the old one properly.

Might be easier in the meantime to keep the name nixnote2. Or do you want to switch to nixnote?
