Package: apt
Version: 0.5.4
Severity: wishlist
It would be good if apt had a 'normalize' command, similar to
'upgrade', but that would downgrade packages automatically also.
For example, suppose someone installed a stable system, then
installed a few packages from 'unstable' to see if some bugs
were fixed. The bugs were not fixed, so they would like to
return the system to entirely stable. The APT sources.list only
contains stable sources, so issuing:
apt-get update
apt-get normalize
would downgrade the appropriate packages back to stable.
Packages not available with /etc/apt/sources.list at all would
have a warning issued, so the user could decide whether to
remove or not (perhaps a --force-removal-of-non-available option
or similar could be added to make this easier?)
Regards,
Andrew.

Downgrades are not supported. Use a snapshotting feature in the file
system or block layer.
