Erro ao instalar o php

Question

Estou tentando instalar o phpMyAdmin no Ubuntu 16.04 LTS.

Etapas seguidas:

1. Apache2 instalado com êxito

2. Toda vez que tento instalar o phpMyAdmin, estou recebendo este erro:

   mysql: [Warning] mysql: Empty value for 'port' specified. Will throw an  
   error in future versions ERROR 1045 (28000): Access denied for user         
   '*<username>*'@'localhost' (using password: YES) . 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  
   

3. Eu tentei usar um ID de login do Ubuntu com privilégios sudo no lugar de. Sem sorte

4. Tentei fornecer outro nome de usuário. Mesmo erro

5. Tentei tentar novamente várias vezes com perguntas. Mesmo erro.

O que devo fazer para corrigir isso? Também gostaria de usar localhost como o servidor (db, web) Obrigado.
