Some people commenting here appear to have bug 1592669. Please follow that bug if you had previously disabled the mysql service.
Different comments from different people clearly relate to different root causes. Developers cannot make progress in understanding or fixing bugs if you mix everything together. So please, unless you are absolutely sure that you have *exactly the same issue* (root cause, not just some symptoms) as the original reporter (Bill), file a separate full report and don't pile on this one. If you don't understand why I'm making this comment, please read "How to Report Bugs Effectively" (https://www.chiark.greenend.org.uk/~sgtatham/bugs.html) first. Thanks! Bill: I'm sorry I can't help further. Please see the essay I linked above. If we cannot reproduce your issue, or figure out how to reproduce your issue, I'm afraid we cannot tell whether your problem was a bug, or if it was something you did to your system that is not expected to work. If you can't tell us exactly what you did such that we can reproduce it either, I'm afraid your report can make no progress, and so I'll set the bug back to Incomplete to make it absolutely clear that nobody should be waiting on progress here, because none is expected. ** Changed in: mysql-5.7 (Ubuntu) Status: Confirmed => Incomplete -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1573624 Title: package mysql-server-5.7 5.7.11-0ubuntu6 failed to install/upgrade: subprocess installed post-installation script returned error exit status 1 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/mysql-5.7/+bug/1573624/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
