The buildd logs from PTS indicate that the package fails to build. -> https://buildd.debian.org/status/package.php?p=qbittorrent
The i386 log says: libboost1.54-dev but it is not going to be installed It appears that libtorrent wants to pull in libboost1.53 while qbt wants 1.54 I did a local pbuilder build and the build finished successfully. pbuilder warned about these 2 dependencies but was able to autoresolve the conflict.
