Right, I've noticed this happens from time to time. However, this way,
most upgrades do work, altough the method used by APT to achieve this
goal is questionable. The current alternative when APT doesn't know how
to upgrade without temporarily breaking dependencies, would be, AFAICT,
to let the users disentangle the situation by hand, as happened in the
Old Times. APT is what we have now, and I don't know any other method
that works as well in general.

(Sorry for stating the obvious... I understand you may wish there were
an alternative to APT that never breaks dependencies)

OTOH, I'm a simple user as far as dpkg, apt and dselect are concerned.
As a consequence, I cannot comment on these design issues with hard,
technical facts to back my claims. I'm subscribed to this list because
I'm interested in seeing what happens to dpkg and dselect, but that's
about it. :)

I see...

Thanks for your comments.
