Comment 3 for bug 1610583

This happened when I was trying to change from Gnome to KDE. It asked me a question that made no sense to this totally inexperienced linux user, and I figured that I had a slightly better chance of being correct if I chose the first of the 2 options. It had something to do with windows [which I need for a few programs], and maybe network managers, but I'm not really sure.

Here's what the terminal looked like when I typed the terminal command to install KDE again:

brian@brian-XPS-8500:~$ sudo apt-get install kubuntu-desktop
[sudo] password for brian:
Reading package lists... Done
Building dependency tree
Reading state information... Done
kubuntu-desktop is already the newest version (1.338).
You might want to run 'apt-get -f install' to correct these:
The following packages have unmet dependencies:
 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).

brian@brian-XPS-8500:~$ apt-get -f install
E: Could not open lock file /var/lib/dpkg/lock - open (13: Permission denied)
E: Unable to lock the administration directory (/var/lib/dpkg/), are you root?

So I can't tell if this is a bug, or if I chose the wrong option when I tried to install KDE. As far as I can tell, I can't get into KDE, I've tried restarting and logging off. Please help.
