我在系统中卸载 Java 时遇到问题。我试过这个如何彻底卸载Java？但我总是遇到同样的错误。
The following packages have unmet dependencies:
default-jre : Depends: openjdk-7-jre (>= 7~u3-2.1.1) but it is not going to be installed
default-jre-headless : Depends: openjdk-7-jre-headless (>= 7~u3-2.1.1) but it is not going to be installed
E: Unmet dependencies. Try 'apt-get -f install' with no packages (or specify a solution).
当我输入时，apt-get -f install 出现此错误：

它说解压档案时出错。在这种情况下，可能是因为下载不正确。删除提到的档案文件并重试：
sudo rm /var/cache/apt/archives/openjdk-7-jre-headless_7u95-2.6.4-0ubuntu0.15.10.1_amd64.deb
sudo apt-get -f install
