من به کمک اینترنت و منابع خارجی تونتم apach,mysql,phpmyadmin رو از ابتدا حذف کنم. 
بعد امدم ابتدا apache و بعد mysql رو نصب کردم. و در آخر امدم phpmyadmin رو نصب کنم که خطای زیر رو داد در انتها:
An error occurred while installing the database:                           
  │                                                                            
  │ ERROR 2002 (HY000): Can't connect to local MySQL server through socket     
  │ '/var/run/mysqld/mysqld.sock' (2) . Your options are:                      
  │  * abort - Causes the operation to fail; you will need to downgrade,       
  │    reinstall, reconfigure this package, or otherwise manually intervene    
  │    to continue using it. This will usually also impact your ability to     
  │    install other packages until the installation failure is resolved.      
  │  * retry - Prompts once more with all the configuration questions          
  │    (including ones you may have missed due to the debconf priority         
  │    setting) and makes another attempt at performing the operation.         
  │  * retry (skip questions) - Immediately attempts the operation again,      
  │    skipping all questions. This is normally useful only if you have        
  │    solved the underlying problem since the time the error occurred.
