For the ones still having problems, check if you have any apt pinning that prevents the libc6 update. For example, you can use "apt-cache policy libc6" to check which version you have installed (marked with "***") and what priority the maverick-updates/main repository is given.
Personally, I had the updates and security repositories set to the same priority through /etc/apt/preferences and ended up getting libc6 stuck at the 2.12.1-0ubuntu10.1 level from the security repository. Commenting out apt pinning preferences for maverick-security and maverick-updates in /etc/apt/preferences (i.e. going back to default priority of 500) and doing aptitude update + aptitude dist-upgrade fixed this problem.
