The VCS repository is not up to date, push the missing commits. high
vcswatch reports that the current version of the package is not in its VCS.
Either you need to push your commits and/or your tags, or the information about the package's VCS are out of date. A common cause of the latter issue when using the Git VCS is not specifying the correct branch when the packaging is not in the default one (remote HEAD branch), which is usually "master" but can be modified in salsa.debian.org in the project's general settings with the "Default Branch" field). Alternatively the Vcs-Git field in debian/control can contain a "-b <branch-name>" suffix to indicate what branch is used for the Debian packaging.
