Answer 1

我认为如果您有多次安装尝试并且mysql.user仍然存在，则可能会发生此错误。我今天遇到了同样的问题。

我已将错误提交为： https://phabricator.wikimedia.org/T177768

使用以下步骤重新安装后问题消失了：

dropping database
removing user from mysql.users
strangely the "user exists" error still appeared on installation
granting access rights was therefore necessary on the mysql database.
