Package: aptitude
Version: 0.4.11.11-1+b1
Severity: wishlist

Hi and thanks for maintaining my favorite package manager!  ;-)


The current behavior of the autoclean command removes from the cache
*any* package which can no longer be downloaded (from currently
configured sources).

This is sometimes risky business:
suppose I pinned package P to version A (for whatever reason, e.g.:
a regression in the newer version B); when version A is no longer
available from the repositories, aptitude autoclean would remove
it from my cache, even though I still have this version installed on
my box; at thet point, if I try to upgrade to a third (even newer)
version C, in order to check whether the regression has been fixed,
I would lose the (easy) possibility to downgrade to version A.

For this reason, I think autoclean should remove packages which
can no longer be downloaded, *unless* they are still installed on
the system.

This wishlist bug is somewhat related to bug #340444, but not
really the same (since it seems that several different suggestions
were sent to #340444,).

I hope my request looks reasonable and may be implemented easily
(and soon!).

Thanks for considering.
