From log (translated as best as I could find):

dpkg: Error while processing the archive: /tmp/apt-dpkg-install-dKWy7w/643-golang-juju-loggo-dev_0.0~git20150318-0ubuntu1_all.deb (--unpack):

 a(z) golang-github-juju-loggo-dev 0.0~git20150527.0.8477fc9-1
also included in package

[Joshua Powers (powersj)]

It appears that the file:
'/usr/share/gocode/src/github.com/juju/loggo/formatter_test.go'
Is provided by both 'golang-github-juju-loggo-dev' and
'golang-juju-loggo-dev' [1].

A simple test case is:

lxc launch ubuntu-daily:zesty z
lxc exec z bash
apt update
apt install golang-github-juju-loggo-dev golang-juju-loggo-dev

To which you will get a message similar to:
dpkg: error processing archive /tmp/apt-dpkg-install-qlSp4o/42-golang-github-juju-loggo-dev_0.0~git20150527.0.8477fc9-1_all.deb (--unpack):
 trying to overwrite '/usr/share/gocode/src/github.com/juju/loggo/package_test.go', which is also in package golang-juju-loggo-dev 0.0~git20150318-0ubuntu1

At the very least these packages should conflict with other another to prevent this error from occurring.
