I just finished verifying the cosmic->disco upgrade (the reproducer). What is important:

- enable -proposed in your sources.list
- add below pinning for it
- install the proposed dpkg

Only then start the upgrade, so that you get a fixed dpkg before and after the upgrade.

Pinning:
# cat /etc/apt/preferences.d/dpkg
Package: dpkg
Pin: release *-proposed
Pin-Priority: 500

Package: *
Pin: release *-proposed
Pin-Priority: -1
