Hello. For Etch, I am using aptitude, rather than apt-get. These seem to be the equivalent commands: apt-get clean = aptitude clean apt-get autoclean = aptitude autoclean apt-get update = aptitude update apt-get upgrade = aptitude upgrade apt-get dist-upgrade = aptitude dist-upgrade So what is the aptitude equivalent of apt-get "check"? (And an extra cookie for your browser if you can explain when to use clean and when to use autoclean . . . ) Thanks.
