在执行apt-get升级时，在升级mysql-server-5.7时，我不断遇到以下错误
以下错误：

Setting up mysql-server-5.7 (5.7.24-0ubuntu0.18.04.1) ...
Checking if update is needed.
Checking server version.
Error occurred: Query against mysql.user table failed when checking the mysql.session.
mysql_upgrade failed with exit status 5
dpkg: error processing package mysql-server-5.7 (--configure):

No apport report written because the error message indicates it's a follow-up error from a previous failure.

 mysql-server depends on mysql-server-5.7; however:
  Package mysql-server-5.7 is not configured yet.

dpkg: error processing package mysql-server (--configure):
 dependency problems - leaving unconfigured
Errors were encountered while processing:
 mysql-server-5.7
 mysql-server
E: Sub-process /usr/bin/dpkg returned an error code (1)

尝试删除mysql server和mysql-server-5.7，出现相同错误。清除也会导致相同的错误
