Package: aptitude
Version: 0.8.3-1
Severity: normal
As every day, I ran "aptitude -u". But for one or two days (not sure if
before or after the APT 1.3 final upload), all Opera APT repos gave a
404. (They no more do, so I can't reproduce it anymore with these repos,
but will later try to get a working and persistent example with a dummy
repo.)
The interesting effect was that if and only if I started "aptitude -u",
it hung at "Loading cache" (no more percentage numbers shown, CPU
idle). I had one aptitude instance "running" in that state for over 12
hours.
strace looked like this with stanzas coming in ca. half-second
intervals:

[...]
What still worked more or less:
* Pressing "q": It prompted me (inside the mini buffer) with y[n], but
pressing "n" did not make the prompt (nor the line it's on) to go away
and the instance then was completely locked. Only Ctrl-C helped then.
* Pressing "q" and then "y" IIRC worked, but not immediately.
* Pressing Ctrl-C and then starting "aptitude" without "-u" worked as
usual (even with new packages and updates) and is what I consider a
workaround.
* Removing or commenting out the broken repositories worked as well and
"aptitude -u" worked as before.
I killed that instance with kill -SEGV to get a core dump. Here's the
backtrace (after pressing "qn" and getting the non-vanishing prompt in
the minibuffer):
Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".
Core was generated by `aptitude -u'.
Program terminated with signal SIGSEGV, Segmentation fault.
