MySQL 5.7 升级无法完成

APT 无法为我升级 mySQL。我认为 1045 错误是由于登录详细信息造成的。我可以运行 mysql_upgrade -uroot -p 并手动完成它，但我该如何告诉 apt 它已完成，请停止尝试？

Setting up mysql-server-5.7 (5.7.24-0ubuntu0.16.04.1) ...
update-alternatives: warning: forcing reinstallation of alternative /etc/mysql/mysql.cnf because link group my.cnf is broken
update-alternatives: warning: not replacing /etc/mysql/my.cnf with a link

我必须使用 /etc/mysql/debian.cnf 中的密码重新创建 debian-sys-maint 用户

GRANT ALL PRIVILEGES ON *.* TO 'debian-sys-maint'@'localhost' IDENTIFIED BY 'PASSWORD';

答案2

如果您在启动时禁用了 mysql 服务，升级脚本将无法完成更新过程。因此，您可以像下面这样在启动时启用 mysql 服务并进行升级，

sudo systemctl enable mysql.service

sudo apt update

sudo apt upgrade -y

如果要在启动时禁用 mysql 服务，可以按如下方式禁用它，

sudo systemctl disable mysql.service
