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
