Dear Meik, Thank you very much for the Mathematica workaround! It worked fine for me, after I had located the package libc6_2.3.1-16_i386.deb at http://ftp.pop-ce.rnp.br/pub/linux/debian/pool/main/g/glibc/ since the apt-get command gave me the new libc6-2.3.2; I just wondered whether there is a more natural place to look for the old package? Best regards, Florian Wagener
