Do you want to continue? [Y/n] Setting up mysql-server-5.7 (5.7.17-0ubuntu0.16.04.1) ... Renaming removed key_buffer and myisam-recover options (if present) mysql_upgrade: Got error: 2002: Can't connect to local MySQL server through socket '/var/run/mysqld/mysqld.sock' (2) while connecting to the MySQL server Upgrade process encountered error and will not continue. mysql_upgrade failed with exit status 11 dpkg: error processing package mysql-server-5.7 (--configure): subprocess installed post-installation script returned error exit status 1 dpkg: dependency problems prevent configuration of mysql-server: 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 No apport report written because the error message indicates its a followup error from a previous failure. Errors were encountered while processing: mysql-server-5.7 mysql-server E: Sub-process /usr/bin/dpkg returned an error code (1) The workaround is to put a `sleep 3` on the 320. line of mysql-server-5.7.postinst script (right before `mysql_upgrade --defaults-file=/etc/mysql/debian.cnf || result=$?` ) The root cause seems to be that invoke-rc.d does not execute systemctl --wait, and systemctl without wait doesn't wait until the database server daemon is up and listening. And of course it could be mitigated by using a systemd socket for mysql.
