Hello Mehdi, 2011/3/10 Mehdi Dogguy <mehdi@debian.org>: > You should not be able to upgrade packages if the dependencies are broken :) What I fear most is an upgrade that would remove some essential OCaml packages on my Debian sid development machine. I know the breakage would be only over a limited period, but I should take into account Murphy's law: it will be at the worst time for me. :-) Best regards, david
