Someone should please correct me if I'm wrong, but I believe the following is the difference: apt-get upgrade will only touch packages which you have already installed. apg-get dist-upgrade will update all packages that you've installed, plus install any new packages required by the later versions. Consider an example: version 1.5 of the foo package requires packages bar and baz. Version 2.0 of foo is released and packaged; this version depends on bar, baz, and quux. If you don't already have quux installed, then apt-get upgrade will not upgrade foo, because it never installs new packages. apt-get dist-upgrade, however, will detect that quux is now required, install that, then upgrade foo. If you already had quux installed for some other reason, then upgrade & dist-upgrade will have the same effect, at least as far as foo is concerned. Given this, it's unclear to me why one would want to use apt-get upgrade. Richard
