从Ubuntu 16.04卸载Mysql 5.7

我在ubuntu 16.04中遇到 mysql 5.7的问题,当涉及到给予用户权限时,所以我想重新安装它,但是当我输入删除MysqL的命令时,我得到以下消息

nato@nato-Compaq-Presario-CQ61-Notebook-PC:~$sudo apt-get remove --purge MysqL-server MysqL-client MysqL-common

distribution that some required packages have not yet been created

The following information may help to resolve the situation:
The following packages have unmet dependencies:
 dbconfig-MysqL : Depends: MysqL-client but it is not going to be installed or
                  mariadb-client but it is not going to be installed or
                  virtual-MysqL-client

E: Error,pkgProblemResolver::Resolve generated breaks,this may be caused by held packages.

我也尝试了以下命令,但结果相同

sudo apt-get remove --purge MysqL*
sudo apt-get autoremove
sudo apt-get autoclean

答案在于错误本身.

dbconfig-MysqL：取决于：MysqL-client但它不会被安装或mariadb-client但是它不会被安装或者是mys-MysqL-client

第一步是删除不允许删除MysqL包的依赖项.

sudo apt-get remove dbconfig-MysqL
sudo apt-get remove --purge MysqL*
sudo apt-get autoremove
sudo apt-get autoclean
