Bug Description

After an upgrade, I got this problem:

dpkg: error processing package libc-bin (--configure):
 subprocess installed post-installation script returned error exit status 139

During several retries and trying several possible solutions I found on the internet, I have seen this as well:
Segmentation fault

This bug was reported in earlier versions of Ubuntu (as far back as 2011). None of the suggestions worked - they included:
apt -f install
dpkg --configure -a
apt autoremove
apt autoclean
apt clean
One solution suggested to remove the broken package, but that would have meant breaking Ubuntu.

I created the following a workaround:

Download the deb file (libc-bin_2.23-0ubuntu10_amd64.deb) from ubuntu package web site ( and save it in /tmp. Trying to install this deb will not work. Extract the contents into an empty folder (e.g. /tmp/fix). With mc (midnight commander) this is pretty easy, but here are some commands that might help.

mkdir -p /tmp/fix/DEBIAN
cd /tmp/fix
ar x ../libc-bin_2.23-0ubuntu10_amd64.deb
tar -xf data.tar.gz
cd /tmp/fix/DEBIAN
tar -xf ../control.tar.gz
cd /tmp
rm control.tar.gz
rm data.tar.gx

In the end, you need to have etc, sbin, usr and DEBIAN folders in /tmp/fix.

If you used mc, you might have INFO and INSTALL - you can delete them.

Move DEBIAN/postinst to some other place (e.g. /tmp)

Now rebuild the package without the postinst script.

cd /tmp
dpkg --build /tmp/fix

You should now have package called build.deb in /tmp. You need to rename it, so use this command:

mv /tmp/build.deb /tmp/fix/libc-bin_2.23-0ubuntu10_amd64.deb

Now install this file:

dpkg -i tmp/fix/libc-bin_2.23-0ubuntu10_amd64.deb
(it should not cause any problems)

Now run the script that was supposed to be run by the installer:

bash /tmp/postinst

Ok, so now you can continue working until the problem has been sorted out.

I attached the repackaged deb - please verify your architecture and version before using it.
