I cannot install phpMyAdmin

Hello. I cannot install phpMyAdmin because all the time I receive the following error:

An error occurred while installing the database:                          │ 
 │                                                                           │

As administrator username I enter ‘root’. As password I enter the MySQL password carefully without any mistakes (I’ve done that 3 times so far. The MySQL password is available the moment I connect through SSH.

I am not sure what is causing the problem or what I should do next.
