I have tried every other solution that I could find on stack overflow and elsewhere on the Internet.
The solutions that i have tried include purging mysql,autoremove,autoclean,dist upgrade,reboot,removing /etc/mysql /var/lib/mysql and almost every other thing that I could find related to this problem.It is not helping me, and now asking this question because no other answers were helping me.I am not worried of losing any DB that I might I have on my system.
I must add that since installing mysql was not working for me,I went with mongodb.It installed fine initally ,but now even removing and installing mongodb is givinf the same Error.
please try the following steps,
1.) First, update the apt package index by typing:
$sudo apt update
2.)Then install the MySQL package with the following command:
$sudo apt install mysql-server
3.)Once the installation is completed, the MySQL service will start automatically. To check whether the MySQL server is running, type:
$sudo systemctl status mysql
