Dear all, I was under the impression that perhaps some versioning issues might be with some packages but seems it's not the case except for the new version of libtorrent-rasterbar-dev. That is the only one which needs to be built as also shared by mikhailnov above.
Just had a look at https://git.launchpad.net/qbittorrent/tree/debian/control?id=3fbd3b3d33bfce3a95e88b3bfb20995e7fd16d38 According to it the latest build-depends has the following - Source: qbittorrent Section: net Priority: optional Maintainer: sledgehammer999 <hammered...@gmail.com> Build-Depends: debhelper (>= 10), dpkg-dev (>= 1.16.1), libtorrent-rasterbar-dev (>= 1.1.2), libboost-dev, libboost-system-dev, qtbase5-dev (>= 5.5.1), libqt5svg5-dev (>= 5.5.1), qttools5-dev-tools, zlib1g-dev According to - [$] apt-cache policy debhelper dpkg-dev libtorrent-rasterbar-dev libboost-dev libboost-system-dev qtbase5-dev libqt5svg5-dev qttools5-dev-tools zlib1g-dev debhelper: Installed: 10.7.2 Candidate: 10.7.2 Version table: 10.7.2+exp.buildlabels 1 1 http://httpredir.debian.org/debian experimental/main amd64 Packages 1 http://httpredir.debian.org/debian experimental/main i386 Packages *** 10.7.2 600 600 http://httpredir.debian.org/debian buster/main amd64 Packages 600 http://httpredir.debian.org/debian buster/main i386 Packages 1 http://httpredir.debian.org/debian unstable/main amd64 Packages 1 http://httpredir.debian.org/debian unstable/main i386 Packages 100 /var/lib/dpkg/status dpkg-dev: Installed: 1.18.24 Candidate: 1.18.24 Version table: *** 1.18.24 600 600 http://httpredir.debian.org/debian buster/main amd64 Packages 600 http://httpredir.debian.org/debian buster/main i386 Packages 1 http://httpredir.debian.org/debian unstable/main amd64 Packages 1 http://httpredir.debian.org/debian unstable/main i386 Packages 100 /var/lib/dpkg/status libtorrent-rasterbar-dev: Installed: (none) Candidate: 1.1.1-1+b2 Version table: 1.1.1-1+b2 600 600 http://httpredir.debian.org/debian buster/main amd64 Packages 1 http://httpredir.debian.org/debian unstable/main amd64 Packages libboost-dev: Installed: 1.62.0.1 Candidate: 1.62.0.1 Version table: *** 1.62.0.1 600 600 http://httpredir.debian.org/debian buster/main amd64 Packages 1 http://httpredir.debian.org/debian unstable/main amd64 Packages 100 /var/lib/dpkg/status libboost-system-dev: Installed: 1.62.0.1 Candidate: 1.62.0.1 Version table: *** 1.62.0.1 600 600 http://httpredir.debian.org/debian buster/main amd64 Packages 1 http://httpredir.debian.org/debian unstable/main amd64 Packages 100 /var/lib/dpkg/status qtbase5-dev: Installed: 5.9.1+dfsg-9 Candidate: 5.9.1+dfsg-9 Version table: *** 5.9.1+dfsg-9 600 600 http://httpredir.debian.org/debian buster/main amd64 Packages 1 http://httpredir.debian.org/debian unstable/main amd64 Packages 100 /var/lib/dpkg/status libqt5svg5-dev: Installed: 5.9.1-2+b1 Candidate: 5.9.1-2+b1 Version table: *** 5.9.1-2+b1 600 600 http://httpredir.debian.org/debian buster/main amd64 Packages 1 http://httpredir.debian.org/debian unstable/main amd64 Packages 100 /var/lib/dpkg/status qttools5-dev-tools: Installed: 5.9.1-2 Candidate: 5.9.1-2 Version table: *** 5.9.1-2 600 600 http://httpredir.debian.org/debian buster/main amd64 Packages 1 http://httpredir.debian.org/debian unstable/main amd64 Packages 100 /var/lib/dpkg/status zlib1g-dev: Installed: 1:1.2.8.dfsg-5 Candidate: 1:1.2.8.dfsg-5 Version table: *** 1:1.2.8.dfsg-5 600 600 http://httpredir.debian.org/debian buster/main amd64 Packages 1 http://httpredir.debian.org/debian unstable/main amd64 Packages 100 /var/lib/dpkg/status @Mikhaelnov, could you do me a favor. could you run the following command and share what it tells you - [$] apt-rdepends --build-depends --follow=DEPENDS libtorrent-rasterbar-dev Reading package lists...
