可以看得出，是这个 linux-image-3.19.0-76-generic 包有问题，依赖或是其它问题，导致apt配置不成功。

编辑 dpkg status 状态文件：

sudo vim /var/lib/dpkg/status

找到包 linux-image-3.19.0-76-generic 和 linux-image-extra-3.19.0-76-generic 那一段，删掉。类似这样：

 packager, and scripts that try to ensure that the system is not left in an
 unbootable state after an update.

 You likely do not want to install this package directly. Instead, install                                                                                             
 the linux-generic meta-package, which will ensure that upgrades work                                                                                                  
 correctly, and that supporting packages are also installed. 

然后再运行

 sudo apt-get install -f 

最后可以清理掉不用的文件，根据上面 linux-generic 包后面的版本号找对应应该删除的文件夹：

rm -rf /lib/modules/3.19.0-76-generic/
rm -rf /boot/*3.19.0-76*
