Fails to build with dpkg-buildpackage

[northivanastan]

I realize this is probably not supported, but since this project had a debian/ directory, and I use vanilla Debian (not Ubuntu), I figured I would try building it with dpkg-buildpackage, instead of the route suggested in the readme, so I could manage it with APT and cleanly uninstall it if necessary.

Unfortunately, this failed with an error:

I decided to report this as an issue because, as it turns out, there's a simple fix for this! The error was merely complaining about the version format in the debian/changelog being incompatible with the source format asserted in debian/source/format. After changing the version number of the latest version listed in debian/changelog from 1.4.8-1 to simply 1.4.8, the package built and installed successfully, and it is currently working on my system. Perhaps future versions should alter the versioning format, or the source format, so that the package can be built as a DEB automatically.

Which Ubuntu version would work on my vanilla Debian (Bullseye)? Dunno, but the build from source looks pretty polished, except for hitting the above issue... which @northivanastan had handily showed me the way around, thanks. The install_debian.sh script had worked too but I was perturbed by the lack of uninstall instructions. Having built and installed the package, removing it got rid of gpservice. One of the signs of trustworthy code, that.
