So in summary, edit /etc/apt/sources.list, replacing sarge or stable in each line with etch or testing and then execute the following: $ apt-get update $ apt-get dist-upgrade [snip] Here a man apt_preferences would help a lot. I was also confused by the way in which packages are chosen from the repositories one has in /etc/apt/sources.list, until I began editing /etc/apt/preferences (for which I took a look at the man page of apt_preferences). I can't say my grasp of the matter is perfect, but this is what I understand: aptitude (or apt-get), when called with the update argument, connects to all of the repositories you specify, and builds, not only a list of available packages, but also different versions (if it finds more than one), the release to which each one belongs, and the preference order of the versions, according to some settings, which give each package version an score. Then aptitude upgrade will install not the newest versions of each package, but the one with highest score. That part about the score is the one you tune with /etc/apt/preferences. In the absence of this file, how does apt know what to install? More or less it installs the newest version it finds in the repositories. If you set your /etc/apt/preferences to giving the Etch packages say 500 points by default, and you have Sid and Etch repositories, and package whatever is 1.1 in Etch, and 1.3 in Sid, then an aptitude update will give the Sid version say 200 points because it is the newest it finds, but then the 500 points the 1.1 Etch starts with win, and you get the Etch package. However, if you had the 1.2 version installed, and aptitude gave the 1.1 Etch version a penalty of -400 points because it is older than the one already installed, then the 1.3 Sid would win 200 vs. 100 (The figures are completely made up by me).

How do you move to testing/etch?
Hi, I've scoured the archives and docs, and googled the globe, but I cannot find an explanation for safely moving - as safe as it can be - from stable/sarge to testing/etch. The Debian Reference has chapter 5, 'Upgrading a distribution to stable, testing, or unstable', but it is non-generic and very much out of date - as well as stating, After properly setting up /etc/apt/sources.list and /etc/apt/preferences as described above you can begin the upgrade., without actually saying what needs to be done. My best guess is to edit /etc/apt/sources.list, and apt-get update, apt- get dist-upgrade, but can anyone point to a good description of the process, please. In addition, is there a written example of adding a package from sid? -- Best, Marc -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of unsubscribe. Trouble? Contact [EMAIL PROTECTED]

So in summary, edit /etc/apt/sources.list, replacing sarge or stable in each line with etch or testing and then execute the following: $ apt-get update $ apt-get dist-upgrade The start of my sources.list file looks like this: deb http://ftp.uk.debian.org/debian/ testing main non-free contrib deb-src http://ftp.uk.debian.org/debian/ testing main non-free contrib deb http://the.earth.li/debian-secure-testing testing/security-updates main contrib non-free deb-src http://the.earth.li/debian-secure-testing testing/security-updates main contrib non-free deb http://security.debian.org/ testing/updates main contrib non-free I'm not sure I really need the last line, but it doesn't seem to do any harm. I think it is only there because I originally installed sarge and then upgraded to testing, which didn't have security updates at that time. In addition, is there a written example of adding a package from sid? I don't know about this. My only experience with sid is accidentally installing it instead of testing, and then finding that nothing worked. Hope this helps, Joe ___ Yahoo!
