+        Downgrading package (as openssl here) due to un-accepting unstable.
+        Dependent package (as rustup here) cannot be rebuilt due to missing
+        keyword, so dependee downgrade is cancelled, but other dependents
+        (such as xwayland here) are rebuilt nevertheless. This should not
+        happen and the rebuilds should be pruned.
