The issue is the contents of your etc/mysql/debian.cnf, then. It should be set up with user=debian-sys-maint and password=something randomly generated.
It could be set up for any user that has the needed privileges for running upgrades, but the idea is that debian-sys-maint will be used by the installation scripts without interfering with other users (and only used for this purpose).
