Some packages could not be installed. This may mean that you have
requested an impossible situation or if you are using the unstable
distribution that some required packages have not yet been created
or been moved out of Incoming.
The following information may help to resolve the situation:


The following packages have unmet dependencies:
 mysql-server : Depends: mysql-server-5.5 but it is not going to be installed

安装mysql时候出现上述错误，

The following actions will resolve these dependencies:


     Keep the following packages at their current version:

2)     libdbi-perl [Not Installed]                        
3)     libterm-readkey-perl [Not Installed]

上述命令提示安装 perlapi-5.14.2

• perlapi-5.14.2

  本虚包由这些包填实: perl-base

  http://packages.ubuntu.com/precise/liblocale-gettext-perl

  用命令安装有问题，到上面网址下载对应的

  perl-base_5.14.2-6ubuntu2.4_amd64.deb (上面下载不到还可以到这里下载

  http://download.csdn.net/detail/maixia24/8417441)

  安装上之后，再执行最初的命令，第一遍会出错，再执行一遍，安装mysql成功。
