Attached to the output from /usr/lib/PackageKit/packagekitd.

PackageKit is not working with the proxy. I configured the the file /etc/PackageKit/PackageKit.conf and NetworkManager. With that patch applied to the previous version, it worked, now it does not.

have you tried the latest version? it should be patched by default

PackageKit 0.6.21-1 is not working with the proxy. I configured the the file /etc/PackageKit/PackageKit.conf and NetworkManager. What would be the correct way?

Ok. Try replacing the current patch with this one (using ABS). If it works for you I'll change the package too

The patch did not work.
The output was:

danielr ~ $ sudo /usr/lib/PackageKit/packagekitd
Failed to load any of the specified backends:: alpm

Sorry, that was a typo. Change "pk_backend_initialize_environment" on line 232 of the patch to "pk_backend_configure_environment."

It worked! Thank you!
Now another problem (I do not know if I have to open another ticket), but how do I disable signature verification?

That is another bug which I have fixed but not packaged up yet. See the first patch I linked at https://bugs.archlinux.org/task/28052

Should be fixed in packagekit 0.6.21-2

dmesg and / var / log / messages.log returned after an upgrade package:

sorry, that isn't enough information for me to work on. if you can reproduce it can you run
# gdb /usr/lib/PackageKit/packagekitd
(as root, make sure no other instances of packagekitd are running first), then type
run
and do whatever it is that causes the crash. Then type
bt
and send me the output. To quit type
q

unfortunately that didn't help much. it would be great if you could rebuild packagekit, but change the PKGBUILD in the following ways:
1) add '!strip' to the options array
options=('!libtool' '!strip')
2) put CFLAGS='-g -O0' at the end of make -s (on line 51)
make -s CFLAGS='-g -O0'

then repeat those gdb commands. Thanks.
Also you might want to just run /usr/lib/PackageKit/packagekitd (as root) first and see if it prints out anything unusual. It will keep running in the background afterwards: to kill it safely use the following command:
dbus-send --system --dest=org.freedesktop.PackageKit /org/freedesktop/PackageKit org.freedesktop.PackageKit.SuggestDaemonQuit

Hopefully this will fix it for you (apply it after the first alpm.patch).

If not it could be tricky to track down:
what packages in particular were you updating when it happened?
is your computer i686 or x86_64?

The patch did not work. The gdb returned:

About the questions:
With any package is the problem.
I have two machines, one i686 and one x86_64, and two in the same problem.

This is really weird. Try this patch instead. Then run /usr/lib/PackageKit/packagekitd (as root) and send me the output (or the last few lines before it crashes at least)

The patch did not work. The packagekitd returned:

(packagekitd:14601): PackageKit-alpm-DEBUG: adding database entry 'devede'
(packagekitd:14601): PackageKit-alpm-DEBUG: writing devede-3.21.0-1 DESC information back to db

The dmesg returned:
packagekitd[14638]: segfault at 41ed ip b7135824 sp b56fe6e0 error 4 in libc-2.15.so[b70f2000+19c000]

It wasn't supposed to work, only to provide me with more information. This one does the same thing, if you could repeat what you did before, but this time just send me the whole output. I take it that it doesn't crash until at least the second package? What happens if you try to update just one package?

Detailing the process.
The settings for the proxy are correct!

The problem is when I update or install a package.

When I update a package, the warning window that appears warning that the system has been updated does not appear, but the package has been updated. At this time the segmentation fault appears already mentioned.

When I install a package, the buttons are locked and gives segmentation fault mentioned, but when I search the package, it is installed perfectly.

Ok, but what about the output? What happens when there is more than one package?

I tested the package with DeVeDe, there are several packages, and it happens the same way as detailed above.

and the output?

The same output above. The problem is the same for both update and to install packages (one or more).

The dmesg returned:
packagekitd[14638]: segfault at 41ed ip b7135824 sp b56fe6e0 error 4 in libc-2.15.so[b70f2000+19c000]

what I mean is: could you apply the latest alpm2.patch and send me the whole output of running packagekitd as root? (see comment dated Saturday, 28 January 2012, 15:07 GMT+12)

I tried to install the package hunspell-de, hunspell and hunspell-en-es to test more than one package.
Dmesg did not return any segmentation fault.

Sorry for the lack of activity. I hope to have some more time to look into this soon. In the meantime I think I may have fixed the progress bar issue on i686. See https://bbs.archlinux.org/viewtopic.php?pid=1058476#p1058476 for details.
