由于一些复杂性，我决定在Ubuntu服务器上重新安装MySQL，这发生在任何人都知道该怎么办？
root@PHost1:~# sudo apt-get remove --purge mysql-server mysql-client mysql-common

Package 'mysql-client' is not installed, so not removed
Package 'mysql-common' is not installed, so not removed
Package 'mysql-server' is not installed, so not removed
You might want to run 'apt-get -f 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 (>= 5.7.22-0ubuntu0.16.04.1) but it is not going to be installed
Depends: mysql-common (>= 5.6.22-1~) but it is not going to be installed
Depends: mysql-server-core-5.7 (= 5.7.22-0ubuntu0.16.04.1) but it is not going to be installed
E: Unmet dependencies. Try 'apt-get -f install' with no packages (or specify a solution).
