dpkg-preconfigure crashed with SIGSEGV in abort()

[James A. Pattie]

Binary package hint: debconf

Running the adept updater via the system tray icon and updating to the latest releases for 7.10 beta, I noticed that when I had it showing me details, I was seeing "stack smashing detected" warnings and then perl was being aborted which corresponds to the packages that failed and caused the errors to be generated. This ultimately caused Adept to error out with the following error "There was an error commiting changes. Possibly there was a problem downloading some packages or the commit would break packages.". I have not yet tried to manually upgrade via apt-get dist-upgrade to see if that fixes anything, though I don't think it will. I'll probably try a reboot and see if any of the packages that had been upgraded just needed to be in a clean state or something.

This was on a fresh install of 7.10 beta2 that I've updated every couple of days as I've had time to play with things.

After rebooting, X refused to start (ie kdm also refused to start). I then tried to do an apt-get dist-upgrade -u, which then gave me an error about libstdc++6_4.2.1-1ubuntu1 not being at the right level and requiring an apt-get -f install to correct. When I tried this it then gave me an error about a corrupt deb tarball. I then deleted the downloaded deb from the cache and it then properly re-downloaded it and installed it and finished installing those packages that were waiting for libstdc++6 to be installed at which time I could then get X/kdm to restart. I'll try the adept updater again next and see if that fixed the problems.

running adept updater gives me the following and then errors out after trying to start installing some packages:

This happende while updating via adept_manager.
But the Update finished ok.

[Hasse Bylov (hassebylov)]

This just happend by it self. I didn't do anything other than starting up KDE...

[Colin Watson (cjwatson)]

What versions of libc6 and libc6-i686 do you have installed?

[Roosje (wilco-roos)]

(2.5-0ubuntu14) is the version that adapt is giving me for libc6

I asked about both libc6 and libc6-i686. They're two packages and I need
the information for both on the same system.

[Roosje (wilco-roos)]

they both have the same version number 2.5-Oubuntu14, i removed libc6-686,
KTorrent is more stable, crashed only twice today.. Sigh, the older version
could run for days without trouble.

Just saw the other posts on my original bug report and thought you might want to know I'm still seeing the occasional "stack smashing detected" output before adept dies and I have to manually go and update things.

I have 2.6.1-1ubuntu9 of both libc6 and libc6-i686 installed at this time.

[dino99 (9d9)]

That version is no more maintained
