Package: libc6-udeb
Version: 2.13-38+deb7u10
Severity: grave
Justification: breaks installation entirely

The wheezy installer fails with anna reporting a segfault:

...
anna[5033]: DEBUG: retrieving libc6-udeb 2.13-38+deb7u10
anna[5033]: DEBUG: retrieving finish-install 2.41wheezy1
anna[5033]: DEBUG: Segmentation fault
anna[5033]: WARNING **: package retrieval failed
kernel: [   66.427372] wget[5382]: segfault a 0 ip 00007176c922c0ca sp 00007ffc8ca83890 error 6 in libresolv-2.13.so[7f76c9222000+13000]

This occurs shortly after libc6-udev is downloaded,
according to the installer interactive display.

Background
----------
I was trying to reinstall an older system with wheezy.
I was using the PXE install image available on 2016-09-08 UTC, at
ftp.au.debian.org/debian/dists/wheezy/main/installer-amd64/current/images/netboot

The mirror shows the last update timestamp as 2016-05-31.
debian-installer/amd64/boot-screens/f1.txt has the fairly useless
build date stamp 20130613+deb7u3+b2.

This installation method was working fine with earlier installer
versions. The breakage has been there some months I'd say.
I only became fully aware of it yesterday.

I don't think the mirror is out of date; I got the same result
with the netboot installer image downloaded from ftp.us.debian.org.


The log above was copied by eye from the console,
I was unable to install the openssh-client=udeb to copy the logs,
thanks to the segfault.

The core of the issue is probably screwed up libc6 versions,
see bugs 740068, 833432

Other package versions that may be of interest
 base-installer: 1.130
 cdebconf-udeb: 0.182
 di-utils: 1.92+deb7u1
 libc6-udeb: 2.13-38+deb7u10
 anna: 1.44+deb7u1

It's really unfortunate to have the oldstable installer break like this.
I hope it can be fixed, age notwithstanding.

Kind regards
Vince

Hi,

It happens this bug has been forgotten in the bts as it is somehow
considered to be reported about the libc6-udeb *source* package. I
believe that since the time the problem is not reproducible anymore.

I am therefore closing the bug, if it can still be reproduced with
recent releases, feel free to reopen the bug.

Regards,
Aurelien
