It's also been fixed (to my understanding) as of apt 1.4.9, which you say you have. So the dist-upgrade does not do anything else "given the apt bug". The basic difference between upgrade and dist-upgrade is that upgrade doesn't remove existing or pull in not-installed stuff, whereas dist-upgrade might. The former is good when you need a box to undergo minimal change; the latter is good when you just want things to "work". The former is probably more suitable for servers, the latter for end-user computers. I usually do "dist-upgrade" out of habit (as I spend most of my time on end-user computers); but "upgrade" might be, at least theoretically, safer. -- Kent West <")))>< Westing Peacefully - http://kentwest.blogspot.com
