JFTR The Arch build port uses this link, when building from tarball instead of git: https://github.com/QupZilla/qupzilla/tarball/v1.4.4 If I should build for Debian I would use the github releases link: https://github.com/QupZilla/qupzilla/archive/v1.4.4.tar.gz I guess both are the same, but you never know.
