我已经安装了 Ubuntu 16.04 LTS，当我想要安装任何软件时遇到此错误：
sudo apt-get install openjdk-7-jre openjdk-6-jre
[sudo] password for ali:

You might want to run 'apt-get -f install' to correct these:
The following packages have unmet dependencies:
google-chrome-stable : Depends: libappindicator1 but it is not going to be installed
openjdk-6-jre : Depends: openjdk-6-jre-headless (>= 6b24-1.11.1-4ubuntu2) but it is not going to be installed
Depends: libgif4 (>= 4.1.4) but it is not going to be installed
Depends: libatk-wrapper-java-jni (>= 0.30.4-0ubuntu2) but it is not going to be installed
Recommends: ttf-dejavu-extra but it is not going to be installed
Recommends: icedtea-netx but it is not going to be installed
openjdk-7-jre : Depends: openjdk-7-jre-headless (>= 7~u3-2.1.1~pre1-1ubuntu2) but it is not going to be installed
Depends: libgif4 (>= 4.1.4) but it is not going to be installed
Depends: libgnome2-0 but it is not going to be installed
Depends: libgnomevfs2-0 but it is not going to be installed
Depends: libgconf2-4 but it is not going to be installed
Depends: libatk-wrapper-java-jni (>= 0.30.4-0ubuntu2) but it is not going to be installed
Recommends: ttf-dejavu-extra but it is not going to be installed
E: Unmet dependencies. Try 'apt-get -f install' with no packages (or specify a solution).
