Create a file called /etc/apt/preferences, and in it, put: Package: * Pin: release a=testing Pin-Priority: 1001 Then, change your /etc/apt/sources.list to point to Etch. Then, apt-get update and apt-get upgrade will attempt to downgrade. You'll probably get a number of errors about a file extisting in a package that already exists in another package. If you do, you'll have to download and install those packages individually with dpkg -I --force-overwrite packagename.deb. When you're all done, if you see any packages in aptitude under "obsolete or locally created packages", those are most likely packages from Sid that aren't in Etch, and you should remove them. Also, don't forget to add security.debian.org to your /etc/apt/sources.list. Finally, remove the /etc/apt/preferences file you created above.
