我想安装Plasma 5.12在我的Ubuntu 16.04.03系统。所以我在终端中运行了以下几行：
sudo add-apt-repository ppa:kubuntu-ppa/backports
sudo apt update && sudo apt full-upgrade
sudo apt update && sudo apt install kubuntu-desktop
然而，在安装过程中，我遇到了一个错误，但我没能记下来。然后我执行了df -h /
Filesystem Size Used Avail Use% Mounted on
/dev/vda1 9.5G 9.0G 81M 100% /
然后我尝试了这个：
sudo apt-get remove --purge kubuntu-*
sudo apt-get remove --purge kubuntu-desktop
sudo apt-get autoremove
sudo apt-get clean
对于上述所有内容，我收到了相同的错误：
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
当然，apt-get -f install也不起作用并给出以下错误：
Unpacking kde-config-telepathy-accounts (4:15.12.3-0ubuntu1) ...

问题:
我该如何解决这个问题？我可以做什么来释放系统上的一些空间并强制卸载kubuntu-desktop？
