Comment 6 for bug 1473149

Bug hit me with Ubuntu 15.10 Beta 2 and now again on today released 15.10.

What I did:
I attempted to apt install kubuntu-desktop on freshly installed system.

What happened:
apt-get failed showing :
Errors were encountered while processing:
 /var/cache/apt/archives/kde-config-telepathy-accounts_4%3a15.08.2-0ubuntu1_amd64.deb
 /var/cache/apt/archives/kaccounts-providers_4%3a15.08.2-0ubuntu1_all.deb
kde-telepathy-minimal: Depends: telepathy-mission-control-5 (>= 1:5.12) but 1:5.16.3-1ubuntu4 is installed
Package system was _completely_ broken. No more software installations or removals possible. apt-get install -f had no effect.
See also thread on this German Ubuntu forum about the broken package system bug:
https://forum.ubuntuusers.de/topic/software-center-nach-installation-von-kde-auss/

At next reboot the system hung displaying only an Oxygen mouse cursor, no login manager appeared. System was completely trashed, not even virtual consoles worked. See also this successor bug: https://bugs.launchpad.net/ubuntu/+source/lightdm/+bug/1473149

What I expected to happen:
A smooth installation of KDE.

What I suspect to be the error:
The KDE package apparently installed incompletely due the bad dependencies mentioned and left the system in a broken state.

What I expect to be done:
Hot Fix: Remove the offending package "kde-telepathy" from metapackage kubuntu-desktop_1.331_amd64.deb.

PATCH INCLUDED:
I made and uploaded a patched kubuntu-desktop_1.331_amd64.deb package file which does not contain kde-telepathy.
To install KDE without destroying your system, download the patched .deb and install it via dpkg -i
