无法启动或删除 MySQL

Question

我在 Ubuntu 15.04 上使用 MySQL 没有任何错误。但是昨天我从昨天的 15.04（15.04 到 15.10 和 15.10 到 16.04LTS）升级到 16.04LTS。我现在有一些问题

当我使用检查 MySQL 状态时

mysqladmin -u root -p status

我收到这个错误

 mysqladmin: Can't read dir of '/etc/mysql/conf.d/' (Errcode: 2 - No such file or directory)
 mysqladmin: [ERROR] Fatal error in defaults handling. Program aborted!

所以我尝试使用删除它

sudo apt-get remove --purge mysql-server mysql-client mysql-common

我收到这个错误

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

由于我是 Ubuntu 的新手，任何人都可以帮助我解决这种情况吗？提前致谢

对我来说，这看起来像是一个依赖问题，所以你可以试试这个：

apt-get autoremove
apt-get remove --purge mysql*
apt-get autoclean
deluser mysql
rm -rf /var/log/mysql
rm -rf /var/lib/mysql
rm -rf /etc/mysql

希望这可以帮助！
