Further to my earlier posting (attached below) I have had some further insight into the problem. It appears that the problem stems from the 'sleep' utility. If I call sleep from the command line with any numeric argument, it outputs 'Illegal instruction'. This appears to be whatever is causing problems with the post-install config of various packages (currently mysql-server and ssh).
The version information for sleep suggests it's part of the GNU sh-utils (version 2.0.11) but I'm not able to find a package that corresponds with an apt-cache search. I have a sneaking suspicion that I could remedy this particular ill if I were able to reinstall/upgrade these utilities. Can anyone help here? Cheers, Ben -- original message -- Hi, I've just started setting up a new Debian box, and after installing from the 3.0r1 woody CD, I switched to using unstable package sources from ftp.uk.debian.org. One of the packages updated as a result of installing Apache was libc6 (2.3.2-8) which failed to install correctly. The output from dpkg (citing a line in libc6.postinst) was something like: Illegal instruction sleep 1 I've tried reverting /etc/apt/sources.list to use stable sources and then manually attempted to install an older version of libc6 (2.2.5-11.5) with dpkg, but this failed with an error message about libdb1-compat. I then began installing a few other packages and the libc6 error (from dpkg) mysteriously disappeared (hence I can't recall it exactly). At first I thought the problem had solved itself, but now I get the same illegal instruction message when attempting to install mysql-server. It appears libc6 is in some way broken. Is there any means by which I can revert to an earlier version of libc6 without catastrophic consequences (I'm aware that it can't just be removed and reinstalled)? Is this a known issue with unstable libc6 (I couldn't find anything with a few googlings, nor in the debian-user archive)? Any help or advice would be much appreciated!
