This bug was fixed in the package unattended-upgrades - 1.10ubuntu5.1 --------------- unattended-upgrades (1.10ubuntu5.1) disco; urgency=medium
* Skip trying to upgrade held packages in call_adjusted() (LP: #1824804) * Follow all kinds of transitive dependencies when adjusting dependencies (LP: #1824804) * Detect unchanged moved conffiles. When a package moves a conffile properly without any change no conffile prompt needs to be shown thus the package can be upgraded unattended even when the conffile is changed locally. (LP: #1823872) * Don't crash collecting transitive dependencies when package has no candidate (LP: #1825886) * Use mark_install_adjusted() in rewind_cache() The original cache had packages marked with adjustments thus rewinding should also do adjustments to reach the same state. Also not using mark_install_adjusted() crashes when apt raises error on held packages.

[Test Case] * test/test_rewind.py is updated to verify that rewinding included adjustments and it is ran during the build. * Also watch the error not happening anymore. [Regression Potential] * The fix is very small and is not likely to cause any regression.
