I’m going to regret this…
Preparing to replace libc6 2.3.2.ds1-22 (using .../libc6_2.3.5-12.1_i386.deb) ... Name Service Switch update in the C Library: pre-installation question. Running services and programs that are using NSS need to be restarted, otherwise they might not be able to do lookup or authentication any more. The installation process is able to restart some services (such as ssh or telnetd), but other programs cannot be restarted automatically. One such program that needs manual stopping and restart after the glibc upgrade by yourself is xdm - because automatic restart might disconnect your active X11 sessions. Known packages that need to be stopped before the glibc upgrade are: xdm kdm gdm postgresql xscreensaver This script did not detect any installed services which need to be stopped. If you want to interrupt the upgrade now and continue later, please answer No to the question below. Do you want to upgrade glibc now? [Y/n] y
