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 ** Attachment added: "Patched kubuntu-desktop_1.331_amd64.deb without the offending subpackage kde-telepathy" https://bugs.launchpad.net/ubuntu/+source/lightdm/+bug/1473149/+attachment/4502637/+files/kubuntu-desktop_1.331_amd64.deb -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to lightdm in Ubuntu. https://bugs.launchpad.net/bugs/1473149 Title: Lightdm refuses to work after installing kubuntu-desktop Status in lightdm package in Ubuntu: Triaged Bug description: After installing kubuntu-desktop meta package I saw a prompt telling me that both sddm and lightdm are available and I am forced to choose one between them.so I chose lightdm.on the next reboot I was unable to use GUI.
