Without looking at the specifics here, usually it's not that an update breaks things, but that it's common for users to have broken their own MySQL installations in various different ways (usually these are experiments rather than production). Then on an upgrade the maintainer script fails when it tries to restart an already failing daemon and it appears that the problem is the upgrade when that wasn't the cause. My view on these is if people can provide specifics of where there actually is a bug in our packaging, then we can fix it, but unless we have that it's not worth wasting time on individual cases except to try and detect a general pattern to find specific use cases that we can actually fix. I'm not sure there are many left though; I suspect that in most cases the steps users actually followed to end up with a failure would not be considered to be supported (eg. installing from third party repositories, customization hacks, and so on). I suspect quite a lot of this is driven by broken third party instructions that users have followed some time in the past. > ### https://pad.lv/1902348 - (New) [mysql-8.0] - package > mysql-server-8.0 8.0.22-0ubuntu0.20.04.2 failed to install/upgrade: > installed mysql-server-8.0 package pre-removal scrip$ subprocess > returned error exit status 1 > > This is actually a different issue!

This is a duplicate of https://bugs.launchpad.net/ubuntu/+source/mysql-5.7/+bug/1490071 I think?
