WARNING: libc upgrade makes system unbootable


Conditions for this to happen are still unclear.

Update/Upgrade your system from a virtual console, without running the xserver.

Ctrl+Alt+F2 to switch to vc 2
sudo invoke-rc.d slim stop
sudo apt-get update
sudo apt-get upgrade
sudo invoke-rc.d slim start

Some #! users have already been hit by this problem.

More info in this thread. Kernel panic on boot after update libc

I am on a 32-bit system and have not had any problem upgrading libc, which seems to be at the root of this.

If you are hit by this, post output of

uname -r 
apt-cache policy libc6 libc6-amd64 libc6-i686

to collect more info on the conditions in which this occurs.

As of now I don't think this has been reported to the Debian Bugs list - I could not find anything.
I can't do it myself since I can't reproduce the error.

As of now it is unclear to me if the situation can be recovered without re-installing.

The remedy for now is

- Make sure to create the root user if you have not done so already

sudo passwd root

- Boot into #! in recovery mode
- Run

sudo passwd root

- Get out of the shell by entering
And your system should complete booting into run-level 2.
