It sounds like openjdk-8 added two Breaks recently, one or both of which
are causing trouble, and none of which fix anything as bad as this.  So
I think we should remove the Breaks on tzdata-java from
openjdk-8-jdk-headless, and remove the Breaks on ca-certificates-java
from openjdk-8-jre-headless.  Would that fix the current issue?

upgrading some packages is way way better than a failed upgrade.
