libc6 update fails: stack smashing detected : /usr/bin/perl

I couldn't update libc6-i686:

$ sudo apt-get install -f

Maybe this bug is related to bug #205079. I had used nvidia-glx-new-envy but after a reboot (with not updated libc6) I had some trouble with the driver and used "nv" instead.

Can you try enabling Apport to get the perl crash details? Edit /etc/default/apport to have "enabled=1", and then:

  sudo /etc/init.d/apport restart

And try the upgrade again.

[FriedChicken (domlyons)]

Apport didn't open automatically but I've attached files from /var/crash.

[FriedChicken (domlyons)]

As this seems to be not fixed till now or is even unfixable(?), I'd like to know if there's a way to make upgrades for the other packages leaving this one out. This package blocks 80 other updates.

[FriedChicken (domlyons)]

I found a fix (or is it just a workaround?). I've done the same as in bug #205079 because the nvidia-glx-new-envy package doesn't seem to be fixed yet.

What I've done:
sudo mv /usr/lib/libnvidia-tls.so.173.14.12 /usr/lib/libnvidia-tls.so.173.14.12.delete
sudo mv /usr/lib/libnvidia-tls.so.1 /usr/lib/libnvidia-tls.so.1.delete
sudo ln /usr/lib/tls/libnvidia-tls.so.1 /usr/lib/libnvidia-tls.so.173.14.12
sudo ln /usr/lib/tls/libnvidia-tls.so.1 /usr/lib/libnvidia-tls.so.1

After that the libc6 package was installable, but 2 other packages could not be configured:

So I guess the real problem behind that is somewhere in perl or libqt-perl.

[FriedChicken (domlyons)]

I've edited /var/cache/debconf/config.dat manually because "sudo dpkg-reconfigure debconf" didn't work anymore, too. I've changed
   Name: debconf/frontend
   Template: debconf/frontend
   Value: Kde
   Owners: debconf
   Flags: seen
to
   [...]
   Value: Dialog
   [...]

That worked, so the problem seems to be in libqt-perl or the qt-frontend of debconf.

[aftertaf (david-wooffindin)]

I confirm the workaround above...

modify the debconf/frontend to use Dialog instead of KDE and this enables a "dpkg -i" to work:

1st try without change:
root@ubuntu:/# dpkg -i /var/cache/apt/archives/debconf_1.5.23ubuntu1_all.deb
(Reading database ... 273978 files and directories currently installed.)
Preparing to replace debconf 1.5.23ubuntu1 (using .../debconf_1.5.23ubuntu1_all.deb) ...
Unpacking replacement debconf ...
Setting up debconf (1.5.23ubuntu1) ...
*** stack smashing detected ***: /usr/bin/perl terminated
dpkg: error processing debconf (--install):
 subprocess post-installation script killed by signal (Segmentation fault)
Errors were encountered while processing:
 debconf

Here I followed the fix mentioned above:
root@ubuntu:/# vim /var/cache/debconf/config.dat

And 2nd try for installing debconf:
root@ubuntu:/# dpkg -i /var/cache/apt/archives/debconf_1.5.23ubuntu1_all.deb
(Reading database ... 273978 files and directories currently installed.)
Preparing to replace debconf 1.5.23ubuntu1 (using .../debconf_1.5.23ubuntu1_all.deb) ...
Unpacking replacement debconf ...
Setting up debconf (1.5.23ubuntu1) ...

Now i hope the beta of intrepid will install, because a lot of dependencies were stuck with this same error or because of packages concerned.....

Say YES !!!

[Kees Cook (kees)]

I can't reproduce the crash (I'm on amd64), but Kde does not load for me (the fix for http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=481642 fixes that for me).

Does anyone who is seeing this crash have a simple way to reproduce it?

[Ernst Kloppenburg (ernst-kloppenburg)]

a similar problem (maybe same cause) was discussed in bug 283942
the debconf kde frontend is dysfunctional partway through the kde3->kde4 transition

[Jean-Baptiste Lallement (jibel)]

Yes, I think so. From this report and duplicates, this bugs only happens with the kde frontend. Thanks you.
