can't install mysql on ubuntu 20.4

Question

I am unable to install mysql server on my linux-20.4 machine.I get the following error:
The following packages have unmet dependencies: mysql-server: Depends: mysql-community-server (= 8.0.27-1ubuntu20.04) but it is not going to be installed E: Unable to correct problems, you have held broken packages.

I have tried deleting and then reinstall several times but got the same result.Then i tried to manually install all the packages. But I got stuck in libaio1 and libmecab2. I did apt-get upgrade but still get the error: Package 'libaio1' has no installation candidate.
This is the first time I am installing mysql.Also I am new to linux.May be I didn't delete existing mysql completely.Please help me install mysql.

Try to install mysql-common and mysql-community-client-plugins both on a single command. It will fix the issue.

sudo apt install mysql-community-client-plugins mysql-common
