Help installing kubuntu-desktop on Ubuntu 16.04

Question

Well, the problem is that I'm trying to install KDE alongside Unity on Ubuntu 16.04. I'm using the command sudo apt-get install kubuntu-desktop* kdm* but I'm not sure if this is correct. If it isn't, please correct me.

Everything goes fine until I have to choose the display manager between lightdm or sddm, no matter what I choose I get an error processing a package kde-telepathy-something.deb.

If I logout and login again I can change to plasma desktop but it doesn't work. It only shows a black screen with nothing I can do. If I try to install KDE again I get an error on a package kde-telepathy-minimal.deb which depends on kde-config-telepathy-accounts (>= 15.04.0) and is not going to be installed.

I'm testing this on a VirtualBox VM before I do it for real on my PC (maybe something has to do with this?).

So, has anyone successfully installed KDE alongside Unity on the new 16.04? Is it not possible yet?

Solution 1

I'm using the command sudo apt-get install kubuntu-desktop* kdm* You should provide specific packages. If it wouldn't help, try following:

sudo  apt-get autoremove -y
sudo apt-get remove --purge kde-telepathy-minimal
sudo apt-get remove --purge kde-telepathy

And run install again. If you will face it again, do following "Unmet dependencies" When trying to install KDE Plasma 5.3 on Ubuntu 15.04 :

sudo dpkg -P unity-scope-gdrive
sudo dpkg -P account-plugin-google
sudo dpkg -P account-plugin-facebook
sudo apt-get install -f

PS: Meanwhile, since the conflicting file is only and icon, it's pretty safe to override the package manager's decision with --force-overwrite:

dpkg -i --force-overwrite kde-config-telepathy-accounts_15.04.0-0ubuntu1~ubuntu15.04~ppa1_amd64.deb

Solution 2

sudo add-apt-repository ppa:kubuntu-ppa/backports
sudo apt-get update
sudo apt-get install kubuntu-desktop

select lightdm as login manager

I have done it successfully. It worked for a few days, then the whole OS started to crush. I would recommend you installing Kubuntu 16.04 itself, kubuntu.org/getkubuntu

Thanks for the response. I couldn't remove telepathy because I kept getting "unmet dependencies". But it worked by removing the unity account plugins BEFORE installing kubuntu-desktop because they conflict with the ones from kde.

I had an error with kaccounts package while installing from backports ppa on fresh 16.04.2, resulting in a black screen, fixed with sudo apt-get install -f , got some random freezes, deinstalled kde-telepathy and kaccounts-* , random freezes seem to be gone.
