It seems that it's already installed but failed during the process. Try removing all previous installations by typing

apt purge mysql-server

and if necessary

apt purge mysql-server-5.7

and then retry the installation by typing

apt install mysql-server

(which is a meta package btw, it will install the latest MySQL Server version)

Whenever I install any package after the installation the same error pops up – HexaCrop Oct 26 '17 at 10:36
Well this must be a problem whith dpkg then. Is your system up-to-date?
```
apt update && apt upgrade
```
What's the output of that?

my system is uptodate but whenever i run those commands, after all the process i get the same error – HexaCrop Oct 26 '17 at 10:52
apparently someone had the same issue and a solution has been given https://askubuntu.com/questions/760724/16-04-upgrade-broke-mysql-server – VinylThePooh Oct 26 '17 at 10:56
but all the step in it is done. And i am still stuck with issue – HexaCrop Oct 26 '17 at 10:59
well, in this case, have you considered using mariadb instead? This works the same appart from the fact that it will stay opensource – VinylThePooh Oct 26 '17 at 11:10
