我已尝试过以下所有内容，但问题仍然存在：
dpkg -S etc/mysql aptitude purge mysql-server --purge-unused sudo apt-get remove --purge mysql-server mysql-client mysql-common sudo apt-get autoremove sudo apt-get autoclean sudo rm -rf /var/lib/mysql sudo rm -rf /etc/mysql sudo dpkg --configure -a sudo apt-get update
我试过这个也没有运气：
sudo apt-get purge mysql-server mysql-client mysql-common mysql-client-5.5 mysql-server-5.5 sudo dpkg -i mysql-5.6.13-debian6.0-i686.deb sudo apt-get install mysql-server
我该怎么办？
使用您尝试的所有命令很难看出系统的实际配置。 您是否按照第一部分的建议阅读了/usr/share/doc/mysql-server-5.5/README.Debian ？
无论如何，我会尝试： sudo dpkg-reconfigure mysql
这将使您有机会输入MySQL的root密码（不要与linux root用户混淆。
如果成功，启动MySQL： sudo service mysql start
