Please try using this command to remove MySQL completely from your current Linux system including your databases, settings and everything else.

apt自动安装添加的存储库中可用的最新版本。
要查看已启用的存储库中的所有可用版本，请运行
apt-cache policy mysql-server
如果输出中未列出要安装的版本，则可能需要添加其他存储库。
来到254 not upgraded部分，这只是意味着存储库中有254个软件包的更新。
您可以使用
sudo apt-get upgrade

尝试从软件管理器中卸载它，然后重新启动系统，它对我有用。
