Disclaimer: I don't currently plat to sponsor this package.
debian/changelog:
- The initial upload needs to close the ITP bug that you have for this
package and have only one changelog entry, with -1 as the Debian
revision.
- "Automated release from GitHub Tag" sounds very wrong to me.
debian/control:
- "Homepage: https://github.com" is wrong.
- Build-Depends: pkg-config should be pkgconf (lintian tells you this).
- S-V is outdated (lintian tells you this).
- "Priority: optional" is the default value (lintian tells you this).
- There is trailing whitespace (lintian tells you this).
debian/copyright:
- "Format: https://www.debian.org" is wrong (lintian tells you this).
- "Source: https://github.com" is wrong.
- "Copyright: 2026 Your Name <your.email@example.com>" is wrong.
debian/rules:
- Changing DEB_BUILD_OPTIONS is prohibited and not needed in your case.
- Some comments, especially "If ninja install still fails due to other
sudo calls, use this", look out of place.
- You are calling dh_installman in override_dh_auto_install.
