This is neither an issue with aptitude nor a bug: As the output says, "zfsutils : Conflicts: zfs-fuse", but libguestfs- tools depends on libguestfs0 which depends on zfs-fuse.
So zfsutils and libguestfs-tools can't be installed at the same time. Which is exactly what aptitude argued about. Closing as invalid. ** Changed in: aptitude (Ubuntu) Status: New => Invalid -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1417051 Title: bug in dependency resolution while installing libguestfs-tools To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/aptitude/+bug/1417051/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
