出现apt 安装版本不兼容的情况：

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:
 apache2 : Depends: apache2-bin (= 2.4.18-2ubuntu3.4) but it is not going to be installed
           Depends: apache2-utils (>= 2.4)
           Depends: apache2-data (= 2.4.18-2ubuntu3.4) but it is not going to be installed
           Recommends: ssl-cert but it is not going to be installed
 linux-image-extra-4.4.0-51-generic : Depends: linux-image-4.4.0-51-generic but it is not going to be installed
 linux-image-extra-4.4.0-93-generic : Depends: linux-image-4.4.0-93-generic but it is not going to be installed
 linux-image-generic : Depends: linux-image-4.4.0-93-generic but it is not going to be installed
                       Recommends: thermald but it is not going to be installed
E: Unmet dependencies. Try 'apt-get -f install' with no packages (or specify a solution).

可以通过图形界面打开system setting ==> software  & Update ==> 勾选Unsupported updates，使之支持不兼容的库。（不可用于工程）
