Comment 2 for bug 1905134

Bug #1685984 suggests there is a bug in dpkg itself that can lead to installation failures with this same message. I'm going to mark this as a dupe of that.

It sounds like it's possible to workaround the issue, though unclear what would work in your case. If you're still having trouble, there are some pointers for community support at http://www.ubuntu.com/support/community that may be able to assist.
