The right question is: why do you have a bittorrent package versioned as 3.4.2-11.4 on your ubuntu system? ubuntu never had such version of the package: https://launchpad.net/ubuntu/+source/bittorrent/+publishinghistory Maybe you installed the debian package, and I'd rather expect such a conflict, but it's not a supported thing.
If I'm wrong, please don't mind reopening this bug and answer to my question. ** Changed in: bittorrent (Ubuntu) Status: New => Invalid -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to bittorrent in Ubuntu. https://bugs.launchpad.net/bugs/1368416 Title: package python-bittorrent 3.4.2-11.5ubuntu1 failed to install/upgrade: trying to overwrite '/usr/share/pyshared/BitTorrent/PiecePicker.py', which is also in package bittorrent 3.4.2-11.4 Status in “bittorrent” package in Ubuntu: Invalid Bug description: Error occured while installing ubuntu recommended update ProblemType: Package DistroRelease: Ubuntu 14.04 Package: python-bittorrent 3.4.2-11.5ubuntu1 ProcVersionSignature: Ubuntu 3.13.0-35.62-generic 3.13.11.6 Uname: Linux 3.13.0-35-generic i686 ApportVersion: 2.14.1-0ubuntu3.3 AptOrdering: python-bittorrent: Install bittorrent: Install python-bittorrent: Configure bittorrent: Configure Architecture: i386 Date: Thu Sep 11 13:34:44 2014 DpkgTerminalLog: Preparing to unpack .../python-bittorrent_3.4.2-11.5ubuntu1_all.deb ...
