Same problem here. To make MySQL start again, I had to manually type the following commands:
sudo mkdir /var/lib/mysql-files sudo chown -R mysql:mysql /var/lib/mysql-files/ sudo chmod 700 /var/lib/mysql-files/ For some reason, updating does not trigger that code in mysql- server-5.5-postinst. I also tried: sudo dpkg-reconfigure mysql-server-core-5.5 and sudo aptitude reinstall mysql-sever-core-5.5 with no success. This was not that easy to find out, because when "sudo service mysql start" is run, no output at all is produced in either of these files: /var/log/mysql.err /var/log/mysql.log /var/log/mysql/error.log Just the following is printed in /var/log/syslog: kernel: [ 5613.296491] init: mysql main process (14542) terminated with status 1 kernel: [ 5613.296500] init: mysql main process ended, respawning kernel: [ 5613.302257] init: mysql post-start process (14543) terminated with status 1 kernel: [ 5613.315931] init: mysql main process (14569) terminated with status 1 kernel: [ 5613.315940] init: mysql main process ended, respawning kernel: [ 5613.317918] init: mysql post-start process (14570) terminated with status 1 kernel: [ 5613.331260] init: mysql main process (14596) terminated with status 1 kernel: [ 5613.331268] init: mysql respawning too fast, stopped And to find the actual cause I had to type: sudo mysqld start -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1637280 Title: Upgrade to 5.5.53-0ubuntu0.14.04.1 fails to start daemon, due to missing secure_file_priv directory To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/mysql-5.5/+bug/1637280/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
