$ sudo service mysql start
 * Starting MariaDB database server mysqld                                        [ OK ] 
 * Checking for corrupt, not cleanly closed and upgrade needing tables.

腐败和威胁我们的maria女士。

$ mysql_upgrade -u panel -p
(略)
Could not create the upgrade info file '/var/lib/mysql/mysql_upgrade_info' in the MySQL Servers datadir, errno: 13

然而，当执行mysql_upgrade进行升级时，会出现上述错误。

$ apt-cache policy mariadb-server
  Installed: 5.5.57-1ubuntu0.14.04.1
  Candidate: 5.5.58-1ubuntu0.14.04.1
  Version table:
     5.5.58-1ubuntu0.14.04.1 0

     5.5.36-1 0
        500 http://archive.ubuntu.com/ubuntu/ trusty/universe amd64 Packages

好像有最新版本的样子。

$ sudo apt-get update
(略)
  mariadb-client-5.5 mariadb-client-core-5.5 mariadb-common mariadb-server
  mariadb-server-5.5 mariadb-server-core-5.5 multiarch-support mysql-common
(略)
$ sudo apt-get upgrade

由于还有其他各种更新内容，所以一起更新了。

$ mysql_upgrade -u username -p
(略)
Could not create the upgrade info file '/var/lib/mysql/mysql_upgrade_info' in the MySQL Servers datadir, errno: 13

然而，最终还是出现了错误。错误代码13是什么原因呢？

#define EACCES          13      /* Permission denied */

以下是来自Qiita文章”搜索errno的值的定义”。听说是与权限有关，所以尝试使用sudo。

$ sudo mysql_upgrade -u panel -p
This installation of MySQL is already upgraded to 5.5.58-MariaDB, use --force if you still need to run mysql_upgrade

看起来需要使用–force选项。

$ sudo mysql_upgrade -u panel -p --force
(略)
OK

因为收到“OK”，所以尝试重新启动MariaDB。

$ sudo service mysql restart
 * Stopping MariaDB database server mysqld                                   [ OK ] 
 * Starting MariaDB database server mysqld                                   [ OK ] 
 * Checking for corrupt, not cleanly closed and upgrade needing tables.

……到底是什么可以接受的呢……顺便说一下，好像这条消息没问题……。

根据1、2、3进行参考。
