您的软件包管理器似乎存在一些问题，这可能是因为源代码已损坏。你能安装其他套餐吗？你正在运行什么样的操作系统？
uname -a
你也可以尝试运行：
apt-get update && apt-get upgrade -y && apt-get dist-upgrade -y
在dist升级后，我可以建议您重启服务器。重启后尝试运行sudo apt-get install tomcat7

我遇到了同样的问题，我的错是安装openjdk9。我删除了所有，然后清除和-f安装。干净之后，只需用sudo apt-get install安装tomcat7，他就得到了他所需要的一切
sudo apt-get remove openjdk*
sudo apt-get purge openjdk*
sudo apt-get autoremove
sudo apt-get -f install
sudo apt-get install tomcat7

遇到同样的问题，找到了一个简单的解决方案。发生这种情况是因为新安装的tomcat无法找到JAVA_HOME。只需转到/ etc / default / tomcat7，取消注释JAVA_HOME变量并为安装的java目录提供正确的路径。
这将解决问题。
