[Bug 1844326] Re: do-release-upgrade crashed with AttributeError in tryMarkObsoleteForRemoval(): 'Package' object has no attribute 'section'

[Brian Murray]

This bug was fixed by the changes in the following upload of ubuntu-
release-upgrader.

ubuntu-release-upgrader (1:19.10.14) eoan; urgency=medium

  * DistUpgrade/DistUpgradeCache.py: New python3-apt bindings no longer provide
    Package.section, so switch to using Package.{candidate,installed}.section
    whenever applicable. This fixes broken partial upgrades. (LP: #1841675)
