Created attachment 62684 [details] screenshot of popup message from muon
apt is still working though
Hi, I suspect that for some reason qaptworker is crashing. It'll be a bit tricky to debug compared to a normal application, though. To get a crash log, this is what you'll have to do: - Install qapt-dbg and gdb, if they're not already installed - In a console, run "sudo gdb qaptworker" - In the gdb console type "run --nofork" - Hit enter, and quickly (within 10 seconds) hit the update button in Muon. If it does crash, the gdb console should say something like: "Program received signal SIGSEGV, Segmentation fault." If it does, type "bt full", and copy/paste the output of that command here. Thanks, Jonathan

That Muon crash is unrelated to the qaptworker one, as has been fixed already in trunk. (Bug 279345, has to do with exiting Muon during an internal reload after the cache update) Thanks for the qaptworker crash log. I'll see what I can do.
Ah, ok. It's a fairly simple case of division by zero. I'll commit a fix when I'm able to get to a computer with commit access later today.
thanks johnathan and kevin ... i opend the bug yesterday and was away from a computer today. saved me some work ... looking forward for the fix G
i tried to reproduce in gdb console and my results were a bit dfferent in fact it said (gdb) run --nofork Starting program: /usr/bin/qaptworker --nofork [Thread debugging using libthread_db enabled] [Inferior 1 (process 5478) exited normally] the same popup message occurs the operation fails (no crash or closing of processes) ... could it be that i am doing something wrong? or is there another problem?
Hmm, about the only thing I can think of is that there was an old copy of qaptworker running when you ran it in gdb, in which case qaptworker will exit normally.
Oh, also make sure not to click update until "[Thread debugging using libthread_db enabled]" appears, or maybe a second or two after. (But still under 10 seconds)
I see that the Synaptic package manager just made this same bugfix yesterday. Something must have changed with the new apt version in Ubuntu 11.10 that exposed the bug (Not checking for division by zero). I've gotten 3 reports of this now, so I think it's safe to say that they're all this bug, even if you end up not being able to get a backtrace. :)

Could you try replacing "int" on lines 169 and 171? I realized that while division-by-zero is the most common floating point error crash, integer overflow is also a SIGFPE.
er, replacing "int" with "unsigned long"
can i do it in runtime ... during debuging or do i need to recompile the package after the changes ? plus line 169 171 of what file ? i not sure think my lines and yours are not numbered the same (a hunch)
Ah, I'm talking about editing src/worker/workeracquireprogress.cpp and recompiling.
yeah thats what i figured ... however in the source i have there is no variable in line 171. appart from that i will try let me know what to do
I meant workeracquire.cpp, oops. :) Change "int ETA = 0;" to "unsigned long ETA = 0;" and "ETA = (int)((TotalBytes - CurrentBytes) / CurrentCPS);" to "ETA = (unsigned long)((TotalBytes - CurrentBytes) / CurrentCPS);"
ok i did just that ... patched, recomiled, reinstalled ... error remains here is the debugging (bt full) output (a bit different from the original) #0 0x006b8638 in __udivdi3 () from /lib/i386-linux-gnu/libgcc_s.so.1 No symbol table info available. #1 0x08056d1b in WorkerAcquire::Pulse (this=0x82250f8, Owner=0xbfffef34) at /home/shani/libqapt-1.1.90/src/worker/workeracquire.cpp:169 packagePercentage = <optimized out> percentage = 0 speed = -1 ETA = <optimized out> #2 0x005165c6 in pkgAcquire::Run(int) () from /usr/lib/libapt-pkg.so.4.11 No symbol table info available. #3 0x00513af7 in ListUpdate(pkgAcquireStatus&, pkgSourceList&, int) () from /usr/lib/libapt-pkg.so.4.11 No symbol table info available. #4 0x08051145 in QAptWorker::updateCache (this=0xbffff78c) at /home/shani/libqapt-1.1.90/src/worker/worker.cpp:210 result = true Lock = <incomplete type> fetcher = <incomplete type> #5 0x0805b131 in QaptworkerAdaptor::qt_metacall (this=0x8068b40, _c=QMetaObject::InvokeMetaMethod, _id=22, _a=0xbffff17c) at /home/shani/libqapt-1.1.90/obj-i686-linux-gnu/src/worker/qaptworkeradaptor.moc:210 No locals. #6 0x0044fce7 in ??

pretty sure ... but just to be on the safe side ... can you let me know exactly what i should do i'll try again when i get back from work tonight. :)
The backtrace shows that you're using the Ubuntu packages, and not a self-compiled version with the fix. I'm fairly sure that this fix should work, so I'll go ahead with the 1.2.0 release tomorrow, and you can see if things work after the upgrade.
sorry about that ... first of all, i did not change the control file when compiling the package, further more i must have inadvertently installed the old packaged when i upgraded. (due to not changing the control file package number was smaller than the package in the repositories. i must have forgot to hold it back when upgrading. so again a thousand apologies for missleading you. i recompiled and tried again ... and it seem to be working. and then downgraded to verify. looking forward for your fix.
No problem. :) It's better to be safe than sorry.

hey ... thanks again for the attention ... installed qapt 1.2 in upgrade ... as expected problem solved ... it was an educational experience for me.
