** Description changed:
- Back tracking stuff to be fixed
+ [Impact]
+ The autoremove command inadvertently removed more packages than necessary as
the manual bit was not correctly moved from meta packages to their dependencies
when the metapackage was being removed due to a dependency being removed.
+
+ [Test plan]
+ APT's rigorous integration and regression test suite will include a fix for
this instance, ensuring it does not happen again.
+
+ [Where problems could occur]
+ The patch changes the code that marks packages for deletion to record that
they were being marked for removal as a result of exhausting all options to
installing them and hence backtracking.
+
+ This means we now pass FromUser=false to the MarkDelete() in more
+ places, which can lead to bugs like
+
+ https://salsa.debian.org/apt-
+
team/apt/-/merge_requests/527/diffs?commit_id=254ba81131a5360b15905dad8174cea640b8736d
+
+ Which cause the translation of the solver result to be incomplete,
+ potentially causing a regression in reporting quality for errors (but
+ not correctness).
+
+ However, while a regression in reporting quality would be unfortunate,
+ removing packages we should not be removing is worse.
