Tried checking for new updates through the update manager and was told that the aptdaemon crashed. Upon retry it worked fine

[Launchpad Janitor (janitor)]

Status changed to 'Confirmed' because the bug affects multiple users.

[Brad Needham (fishrcynic)]

synaptic crashes quite regularly due to this

[Robert Roth (evfool)]

Raising the importance to High because of the high number of duplicates, as all packages using libapt seem to be affected.

[Michael Vogt (mvo)]

This started on 2011-09-20, that is the day when 0.8.16~exp5ubuntu10 got uploaded.

[Michael Vogt (mvo)]

But 0.8.16~exp5ubuntu10 got not accepted before the 22th, so that is unlikely.

Aptdaemon got update on the 19th to 0.43+bzr697 but the changes there do not look releated at all.

[Michael Vogt (mvo)]

Plus synaptic (e.g. bug #859355) is affected as well so its unlikely that aptd itself is the problem.

Can someone try to reproduce this problem using a terminal (e.g. gnome-terminal) please:
It would be nice to know if
$ sudo apt-cache gencaches -o Debug::pkgCacheGen=true
crashes.

[Mad Maks (mad.maks)]

$ sudo apt-cache gencaches -o Debug::pkgCacheGen=true

does not crash on my machine

Did not crash for me. (Latest updates checked and applied imediately
before test).

sudo apt-cache gencaches -o Debug::pkgCacheGen=true

gives

...loads of lines simialr to those below...

Hope this helps

[Evan Huus (eapache)]

I just saw this again after updating and rebooting.

apt-cache madison reports:
apt | 0.8.16~exp5ubuntu12

So I do have the version which was supposed to contain a fix.

[Mauricio Pretto (pretto)]

just got it today after couple of hundred updates

[Michael Vogt (mvo)]

This is fixed in apt now, I close the update-manager task.

[Shock (mmiron)]

It happened again today. How is this fixed?

[Jonathan Thomas (echidnaman)]

I've gotten a report of this in 12.04: https://bugs.kde.org/show_bug.cgi?id=299800

Since it doesn't seem to be fixed, I'm re-opening the bug.

[Brian Murray (brian-murray)]

We can see this still occurring regularly with later releases of Ubuntu at the Ubuntu Error Tracker.

https://errors.ubuntu.com/problem/1859029e9f0d88ba0e587718572a0d57e56f72c6

[Brian Murray (brian-murray)]

Bug 957231 is the most recent occurrence of this crash.

[Mathew Hodson (mhodson)]

Should this be marked Fixed now that Bug #957231 is fixed?

[Julian Andres Klode (juliank)]

Marking as fixed, as bug 957231 is marked fixed.
