Subject: aptitude: Segmentation fault

Package: aptitude
Version: 0.4.1-1
Severity: grave

When trying to update the packages list (pressing "u" in the GUI)
today, I got this warning:

,----
| W: GPG error: http://ftp.de.debian.org sid Release: The following signatures couldn't be verified because the public key is not available: NO_PUBKEY 010908312D230C5F
| W: GPG error: http://ftp.de.debian.org experimental Release: The following signatures couldn't be verified because the public key is not available: NO_PUBKEY 010908312D230C5F
`----

Nevertheless, I started the upgrade ("U", "g" in the GUI).

aptitude told me:
  "Some packages were broken and have been fixed:...".

I didn't change anything in the list presented to me and told it to
start the upgrade ("g").

aptitude told me:
  "WARNING: untrusted version of the following packages will be
   installed!..." with a list of packages.

I selected "Abort Installation", exited the Preview buffer ("q") and
tried to update the package list again. aptitude exited with a
segmentation fault:

,----
| Ouch! Got SIGSEGV, dying..
| Segmentation fault (core dumped)
`----

I saw very little in the GUI just before the crash, but it appeared as
if the download of the first file had been started.

I have uploaded the core files (core.23303, core.23498) to
<http://www.hilluzination.de/stuff/debian/aptitude/>.

Cheers,
-Hilko

I have been able to reproduce this bug in a simpler setting. Calling
aptitude with an up-to-date package list, I immediately started the
upgrade ("U", "g"), exited the Preview buffer ("q"), and updated the
package lists again ("u"). Segmentation fault.

I have uploaded the resulting core file core.23873 to the same place.

I'm unable to reproduce this problem, the steps work fine for me.

[totya (totya)]

Today I downloaded the kubuntu edgy alternate iso (kubuntu-edgy-20060811). I installed server (so I choosed the install-server menu instead of the kubuntu-desktop) on my machine. The installation went fine.

After I finished the installation, I replace my sources.list file with this one:

# main restricted universe multiverse
deb http://de.archive.ubuntu.com/ubuntu edgy main restricted universe multiverse
deb-src http://de.archive.ubuntu.com/ubuntu edgy main restricted universe multiverse

# updates main restricted universe multiverse
deb http://de.archive.ubuntu.com/ubuntu edgy-updates main restricted universe multiverse
deb-src http://de.archive.ubuntu.com/ubuntu edgy-updates main restricted universe multiverse

# security main restricted universe multiverse
deb http://security.ubuntu.com/ubuntu edgy-security main restricted universe multiverse
deb-src http://security.ubuntu.com/ubuntu edgy-security main restricted universe multiverse

I run:

apt-get update
aptitude install openssh
aptitude install ssh

This part went fine too.

After fire up aptitude in ncourse mode, to change the dependecy handling. I switched off the dependecy handling/Remove unused packages automatically.

After I typed:

# aptitude install kubuntu-desktop

So I also encountered this problem.

However check this out:

You can find the strace output in the attachment.

I created the trace output this way:

strace -o /tmp/aptitude.trace aptitude install kubuntu-desktop

root@penge:/tmp# dpkg -l | grep aptitude
ii aptitude 0.4.1-1.1ubuntu2 terminal-based apt frontend

I think my problem is the same as Bug #55900:

[Michael Vogt (mvo)]

I close this bugreport because:
a) the imported debian bug is fixed
b) the other segfault is fixed with the patch from Bug #55900
