[Bug 1682934] Re: package python3 3.5.1-4 failed to install/upgrade: pre-dependency problem - not installing python3

[Dave Kuhlman]

I attempted to upgrade to Ubuntu 17.04 zesty.  That seems to have
failed.  Now, when I do `sudo aptitude full-upgrade`, I get the
following error messages:

# =====================================================================
The following packages will be upgraded:
  python3
The following partially installed packages will be configured:
  gedit python3-minimal python3-uno python3.5 python3.5-minimal
  rhythmbox-plugin-magnatune rhythmbox-plugins ubuntu-gnome-desktop
1 packages upgraded, 0 newly installed, 0 to remove and 0 not upgraded.
Need to get 0 B/8,696 B of archives. After unpacking 0 B will be used.
Do you want to continue? [Y/n/?]
