Kubuntu 16.04上的MySQl 5.7安装失败

Question

Configuring mysql-server-5.7 (5.7.11-0ubuntu6) … 
insserv: warning: current start runlevel(s) (empty) of script `mysql' overrides LSB defaults (2 3 4 5). 
insserv: warning: current stop runlevel(s) (0 1 2 3 4 5 6) of script `mysql' overrides LSB defaults (0 1 6).
mysql_upgrade: Got error: 2002: Can't connect to local MySQL server through socket '/var/run/mysqld/mysqld.sock' (2) while connecting to the MySQL server 
Upgrade process encountered error and will not continue. 
mysql_upgrade failed with exit status 11 
dpkg: error with
   mysql-server-5.7 (--configure):

apt-get remove返回相同的结果.

从15.10升级到16.04会出现此错误

Answer 1

对我来说完全相同:运行级别警告和mysql_upgrade错误.

我想这是因为我禁用了mysql服务,启用它修复了问题:

sudo systemctl enable mysql

Answer 2

手动删除MySQL服务器的所有文件
