Impossible d'installer Kile(LATEX) dans ubuntu 16.04

J'essaie d'installer kile à l'aide de la commande suivante

sudo apt-get install kile

l'erreur est affichée

Some packages could not be installed. This may mean that you have
requested an impossible situation or if you are using the unstable
distribution that some required packages have not yet been created
or been moved out of Incoming.
The following information may help to resolve the situation:

The following packages have unmet dependencies:
 kile : Depends: kde-runtime (> 4:4.10) but it is not going to be installed
E: Unable to correct problems, you have held broken packages.

J'ai ensuite essayé cette commande pour ajouter le PPA

sudo add-apt-repository ppa:kile/stable

l'erreur est affichée

sudo: add-apt-repository: command not found"

Pour résoudre ce problème, j'ai exécuté

sudo apt-get install software-properties-common python-software-properties

puis il affiche à nouveau un message d'erreur

Package software-properties-common is not available, but is referred to by another package.
This may mean that the package is missing, has been obsoleted, or
is only available from another source

E: Package 'software-properties-common' has no installation candidate

Veuillez m'aider à résoudre ce problème.
