我是 Ubuntu 新手。我在终端中输入了以下几行：
sudo add-apt-repository ppa:scribus/ppa
sudo apt update
sudo apt install scribus-ng
前两个代码可以运行，但第三个语句的结果如下：
sudo apt install scribus-ng
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:
libmetacity-private3a : Depends: metacity-common (= 1:3.18.7-0ubuntu0.3) but 1:3.18.7-0ubuntu0.2 is to be installed
scribus-ng : Depends: python-tk but it is not going to be installed
Depends: scribus-ng-data (= 1.5.2-0ubuntu16.04.0~ppa0) but it is not going to be installed
Depends: libgraphicsmagick-q16-3 (>= 1.3.5) but it is not going to be installed
Depends: libopenscenegraph100v5 but it is not going to be installed
Depends: libpodofo0.9.3 but it is not going to be installed
Recommends: fonts-dejavu but it is not going to be installed
Recommends: icc-profiles-free but it is not going to be installed
E: Unmet dependencies. Try 'apt-get -f install' with no packages (or specify a solution).
我遇到了这个错误。我该如何解决它？
