[Bug 1324196] Re: upgrade from 12.04 to 14.04 not possible

[Brian Murray]

You've installed python3 packages from a PPA which is preventing the
upgrade, as the package versions are greater than those in Trusty, to
14.04.

libpython3.4 3.4.0-2ubuntu1irie1~precise1 1
libpython3.4-minimal 3.4.0-2ubuntu1irie1~precise1 1
libpython3.4-stdlib 3.4.0-2ubuntu1irie1~precise1 1


** Summary changed:

- upgrade from 12.04 to 14.04 not possible
+ upgrade from 12.04 to 14.04 not possible due to python3 from a PPA
