By default, version comparison in Debian and other packaging systems are not alphanumeric, but each part of the version. Debian has some features to amend versions, like + and ~. If you are not sure, just try it with dpkg --compare-versions [1] Also see debmake-doc [2] Best Regards Markus Frosch [1] https://manpages.debian.org/unstable/dpkg/dpkg.1.en.html [2] https://www.debian.org/doc/manuals/debmake-doc/ch05.en.html#name-version
