Hi, first of all on the title: " Also data files are located on NTFS partition so that MySQL server on windows server installation can also access same data files"
That IMHO is a typical "might work but should not be relied on" case. For example on upgrades mysql might upgrade the database, that makes the other one not working on it correctly (best case) or shred your data (worst case). Anyway this isn't what the bug is about. >From the log: [...] mysql_upgrade: Got error: 1045: Access denied for user 'debian-sys-maint'@'localhost' (using password: YES) while connecting to the MySQL server Upgrade process encountered error and will not continue. And this is just such an "upgrade DB on program upgrade" that is failing. This user is created on DB installation as a service user to do these things. Maybe on your setup you accidentally dropped that user (or use DB file created by windows mysql which never had it). In any of those cases the upgrade can't continue. You might add the user to your setup - you can check /var/lib/dpkg/info/mysql-server-5.7.postinst how it usually is done. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1746826 Title: could not upgrade mysql during lubuntu upgrade process from v 17.04 to 17.10 - Also data files are located on NTFS partition so that MySQL server on windows server installation can also access same data files To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/mysql-5.7/+bug/1746826/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
