You might want to run 'apt --fix-broken install' to correct these.
The following packages have unmet dependencies:
mysql-server-5.7 : PreDepends: mysql-common (>= 5.5) but it is not going to be installed
Depends: mysql-client-5.7 (>= 5.7.25-0ubuntu0.18.04.2) but it is not going to be installed
Depends: mysql-common (>= 5.8+1.0.4~) but it is not going to be installed
Depends: mysql-server-core-5.7 (= 5.7.25-0ubuntu0.18.04.2) but it is not going to be installed
E: Unmet dependencies. Try 'apt --fix-broken install' with no packages (or specify a solution).
by running this sudo apt install mysql-server command.
