The "trying to overwrite" error seems to be because you are going from the upstream packages to the native ones, and they're a bit different in which packages have some of the files. So it's probably the apt-get purge command that fixed it (unless you tried that on its own before without luck?), since that would remove the conflicting files from the 14.04 package.
