How to upgrade glibc on Debian?

I was able to install libc6 2.17 in Debian Wheezy by editing the recommendations in perror’s answer:

You need to exit out of your display manager by pressing CTRLALTF1.
Then you can stop x (slim) with sudo /etc/init.d/slim stop

(replace slim with mdm or lightdm or whatever)

Add the following line to the file /etc/apt/sources.list:

deb experimental main

Should be changed to:

deb sid main

Then follow the rest of perror’s post:

Update your package database:

apt-get update

Install the glibc package:

apt-get -t sid install libc6-amd64 libc6-dev libc6-dbg

After done updating libc6, restart computer, and you should comment out or remove the sid source you just added (deb sid main), or else you risk upgrading your whole distro to sid.
