[debian-mysql] Bug#847992: mysql-server-core-5.6 upgrade to stretch fails with file conflict on innochecksum.1.gz

[Gabriel Filion]

Package: mysql-server
Version: 5.5.53-0+deb8u1
Severity: important

Hello,

I'm trying to upgrade from jessie to stretch and I'm getting blocked on the
mysql upgrade from 5.5 to 5.6

During the upgrade I get this error message:

dpkg: mysql-client-5.5: dependency problems, but removing anyway as you requested:
 mysql-server-5.5 depends on mysql-client-5.5 (>= 5.5.53-0+deb8u1).

Because of the previous error messages, there seems to be either a
dependency/breaks issue or something that's not happening right during removal
of mysql-server-core-5.5

A workaround is to apt remove mysql-server-5.5, then apt install
mysql-server-5.6

I've set this to priority Important since the upgrade path from jessie to
stretch is broken because of this.
