[Bug 1794057] Re: package mysql-server-5.7 5.7.23-0ubuntu0.16.04.1 failed to install/upgrade: subprocess installed post-installation script returned error exit status 1

[Andreas Hasenack]

Thanks for filing this bug in Ubuntu.

Unfortunately it's not clear why the package installation failed:
(...)
mysql.user                                         OK
The sys schema is already up to date (version 1.5.1).
Checking databases.
Error occurred: Error during call to mysql_check.
mysql_upgrade failed with exit status 4
dpkg: error processing package mysql-server-5.7 (--configure):
 subprocess installed post-installation script returned error exit status 1

The error log is also unhelpful. Looking at the source, status 4 means:
  EXIT_MYSQL_CHECK_ERROR = 4,
    EXIT_MYSQL_CHECK_ERROR - Error during calling mysql_check functionality.


Does the error persist if you try the following:

sudo apt update
sudo apt -f install


If yes, can you try running the upgrade command on its own, like this, as root:

mysql_upgrade --defaults-file=/etc/mysql/debian.cnf


Thanks
