我想在 Ubuntu 16.04 中重新安装 mysql。
mysql-server is already the newest version (5.7.21-0ubuntu0.16.04.1).
You might want to run 'apt-get -f install' to correct these:
The following packages have unmet dependencies:
mysql-server : Depends: mysql-server-5.7 but it is not going to be installed
E: Unmet dependencies. Try 'apt-get -f install' with no packages (or specify a solution).
在此之后，我编写了一个删除 mysql 的代码，但它并没有被删除。
sudo apt-get purge mysql-server mysql-client mysql-common mysql-server-core-* mysql-client-core-*

您可以尝试以下步骤：

mysql-server将从您的系统中删除。apt-get autoremove mysql-server检查您是否还
mysql安装了。mysql -V这将安装 mysql-server
apt-get install mysql-server

dpkg-reconfigure mysql-server
