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

The following information may help to resolve the situation:

The following packages have unmet dependencies:
 mysql-client-core-5.6 : Breaks: mysql-client-core-5.5 but 5.5.54-0ubuntu0.14.04.1 is to be installed

If I use: apt-get install mysql-client-core-5.6 or mysql-client-core-5.5 , can successfully to install , but don't to connect mysql server .

mysql -h127.0.0.1 -uxxx -pxxx

ERROR 2003 (HY000): Can't connect to MySQL server on '' (111)
ERROR 2003 (HY000): Can't connect to MySQL server on '' (111)

I hope to install mysql-client-core-5.6 than mysql-client-core-5.5.

I suggest running sudo apt-get clean && sudo apt-get autoclean && sudo apt-get autoremove && sudo apt-get update to clear old packages lingering on your system, and then updating the sources. Then install the program.
