Команда 'mysql' не найдена, но может быть установлена ​​даже с уже установленной, что может привести к возможным ошибкам?

Итак, проблема началась с этого.

  1. Мне не удалось войти в mysql, поэтому я полностью удалил его, используя следующие команды в Ubuntu 18.04. 
$ sudo apt-get remove --purge mysql-server mysql-client mysql-common -y
$ sudo apt-get autoremove -y
$ sudo apt-get autoclean

$ rm -rf /etc/mysql

$ sudo rm -rf /etc/mysql

2. Затем я сделал новую установку, используя следующие команды 

$ sudo apt install mysql-server

Но у меня проблемы. 

~$ sudo mysql_secure_installation
sudo: mysql_secure_installation: command not found

и 

$ mysql

Command 'mysql' not found, but can be installed with:

sudo apt install mysql-client-core-5.7   
sudo apt install mariadb-client-core-10.1```

Я новичок в Linux, можете ли вы указать, что я сделал неправильно и как решить проблему.
