Problem with apt after installing kde?

Question

linux

In general, I wanted to install KDE on Ubuntu 16.04. But instead of sudo apt install plasma-desktop, I wrote sudo apt install kubuntu-desktop . As a result, everything was installed, but I could not enter KDE. After logging in - just a black screen. But it enters the default DE normally. But now there is a huge problem - when you try to install anything from the terminal, you get this mess:

Reading package lists... Done
Building dependency tree
Reading state information... Done
You might want to run 'apt-get -f install to correct these:
The following packages have unmet dependencies:
gdebi : Depends: gdebi-core (= 0.9 .5.7ubuntu1) but it is not going to be installed
Depends: gksu but it is not going to be installed
Depends: gnome-icon-theme but it is not going to be installed
kde-telepathy-minimal : Depends: kde-config- telepathy-accounts (>= 15.04.0) but it is not going to be installed
E: Unmet dependencies. Try 'apt-get -f install' with no packages (or specify a solution).

If you enter

apt-get -f install

- offers to download the package for 869kb. But if you agree, he says that the error is in some subprocess. What can be done here? How to at least make it so that you can install something, well, it is desirable to remove this Kde-desktop.

Answer 4

Remove the gdebi package . All the same, this program was created for Gnome. You can uninstall it like this:
Then, if necessary, continue the installation with the command:
If you need a graphical program for installing packages, try plasma-discover or what kind of package manager is there in Kubuntu?
PS Although it turns out there is a gdebi for KDE.
