Public bug reported:
[Impact]
* Unattended-upgrades tries to mark packages for upgrade and when it
fails to do so and falls back to mark adjusting packages to use
candidates from allowed origins it can spend a lot of CPU time on
packages which are not installable in the end.
[Test Case]
* Mark an upgradable package from the security pocket as held.
* Observe u-u adjusting only direct dependencies, instead of doing it
recursively.
[Regression Potential]
* U-u may fail to install updates due to APT not finding a solution
without having transitive dependences adjusted. In those cases the
update should mark the transitive dependencies which enable the update
as direct dependencies.
** Affects: unattended-upgrades (Ubuntu)
Importance: Undecided
