Thanks for filing the report with us. Do you have any logs or messages from when you first attempted to upgrade mysql that indicated why the upgrade fail? You have done some great work on trying to get around it, but I would like to understand what caused the original upgrade to fail.
We have a number of reports where an upgrade will fail because the service is not quite up yet, you can see LP: #1592669 for more information there. I have a feeling this is yet another example of that bug, but wanted to confirm that first. ** Changed in: mysql-5.7 (Ubuntu) Status: New => Incomplete -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1686894 Title: mysql-server hangs on postinst script To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/mysql-5.7/+bug/1686894/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
