By doing this you probably did a partial distribution upgrade to Debian unstable and changed some basic packages like libc6. If you want upgrade to unstable, you should do a "apt-get dist-upgrade". To test the effects of this before doing the dist-upgrade, run "apt-get --simulate dist-upgrade". If all you want to do is install a newer version of a package than exists in the Debian release, you should try to install a backport of the package. One place to look for these is http://www.apt-get.org/. > This got me back more or less to where I started, I think, but now when > the system boots, xdm will not run. I don't use xdm, but look for a xdm-errors or your .xsession-errors file to get more info on what the problem. You may not be back at your starting woody distribution. "cat /etc/debian_version" to see what your distribution is reported as. If you want to try to undo the upgrade, I think you will need to create a /etc/apt/preferences that contains: Package: * Pin: release a=stable Pin-Priority: 1001 see "man apt_preferences" for more details. > > Also, the "sleep" command produces an "illegal instruction" message.

Yes, but if you don't want to upgrade your distribution to unstable, you should probably set pin-priorities or run apt-get with options -u or -s. -- Jerome
