If you're on 12.04 or 10.04, you don't need to do anything special to upgrade. The usual procedure applies:
sudo apt-get update
sudo apt-get upgrade
Or, specifically:
sudo apt-get install libc6
To verify, run apt-cache policy
:
$ apt-cache policy libc6
libc6:
Installed: 2.15-0ubuntu10.10
Candidate: 2.15-0ubuntu10.10
Version table:
*** 2.15-0ubuntu10.10 0

100 /var/lib/dpkg/status
2.15-0ubuntu10.9 0

The USN notice is more cautious, and given the core nature of libc
, I second it:
After a standard system update you need to reboot your computer to make
all the necessary changes.
