Hi Halil, thanks for the report. On upgrade the package needs to check and ensure it can upgrade the database correctly. To do so it connects as root and this seems to fail in your case.
>From your log: Processing triggers for dbus (1.10.6-1ubuntu3.3) ... Setting up mysql-server-5.7 (5.7.20-0ubuntu0.16.04.1) ... mysql_upgrade: Got error: 1045: Access denied for user 'root'@'localhost' (using password: NO) while connecting to the MySQL server Upgrade process encountered error and will not continue. mysql_upgrade failed with exit status 11 It uses mysql_upgrade running as the debian-sys-maint user, which it creates on installation and attempts to maintain for this purpose. That seems to fail now - maybe you have reconfigured some of the access to your mysql ? There are some workarounds of people facing the same that I recommend to follow in [1][2]. Since I can't guess what part you have changed I finally recommend considering debugging with [3] knowing about the debian-sys-maint user as I mentioned above.
