No, this will upgrade any "upgradeable" packages - be it a security update or not. > one more question. for example. if i wanted to upgrade. but only to > stable version not to unstable or testing. then what could be done to > achieve this. if there is no stable version update then it shouldn’t > download anything from servers. You don't upgrade stable to stable, you upgrade certain packages within the stable distribution - the above command will achieve just that. > what i want is not just security patch but also OS to OS upgrade but > only stable releases > for, example. lenny to new lenny (but stable version) I don't quite get what you mean by Lenny to new Lenny?

Lenny to squeeze upgrade is somewhat different, you need to have entries for both of these releases in you sources.list file(s). aptitude update && aptitude full-upgrade will do what you want here. Bear in mind that full-upgrade will remove packages, i.e. the ones which are in conflict with the new ones. > >> 3. how to revert back to old OS, for example, in my case i upgraded my > >> system from 6.0.4 to Wheezy/SID now want to revert things back. > > > > You can always install an older version of the package. > > > > [0] It seems like you had several entries in your sources.list file(s) > > - post the content of your file here. > > deb http://security.debian.org/ squeeze/updates main > deb-src http://security.debian.org/ squeeze/updates main > deb http://backports.debian.org/debian-backports squeeze-backports main > deb http://ftp.de.debian.org/debian sid main This is the mistake you made, you've mixed both squeeze (stable) with sid (unstable release) adding squeeze-backports on top of it. I'd recommend reading about mixing of stable, testing unstable - stay away from experimental ;^) - releases and what can you do with APT pinning. Until then, stick with stable.
