lib32-qt4 upgrade brakes Skype client...

bjorntj · 2016-10-24 18:30:41

After upgrading to version 4.8.7-5 og lib32-qt, I get the following error when trying to start Skype...:

/usr/lib32/skype/skype: error while loading shared libraries: libQtWebKit.so.4: cannot open shared object file: No such file or directory

Downgrading to version 4.8.7-4 makes it work again.... Is this a known bug/feature?

Regards,

BTJ

I get the same problem today. I'm not sure we can hold out much longer from moving to skypeforlinux-bin.

PS: Actually, according to https://wiki.debian.org/skype legacy skype can not message or call people using new version so maybe not much point using legacy skype anyhow?

You mean lib32-qt4, right (not lib32-qt)? I'm trying to troubleshoot, but I can't downgrade to lib32-qt4 4.8.7-4 because it requires lib32-sqlite3, and this no longer appears to be available.

@bulletmark I just used skype a few days ago before this update and it worked fine chatting and video calling the latest OS X version.

lib32-sqlite provides lib32-sqlite3 package name, well at least it did in the previous version. So you need to downgrade lib32-sqlite first and then downgrade lib32-qt4.

Ah, right. Thanks for that.

So skype is complaining about the lack of libQtWebKit.so.4. This file is installed at /usr/lib32/libQtWebKit.so.4 by the older lib32-qt4 4.8.7-4, but it's not installed at all by the newer lib32-qt4 4.8.7-5. I looked at the difference between these two versions, but the only change was in dependencies. There shouldn't be any changes in the files installed!

Comparing the two installed packages at `/var/cache/pacman/pkg`, there were 48 files missing from the newer lib32-qt4 4.8.7-5, in `/usr/include/qt4-32` and `/usr/lib32`. I have no idea why, so I compiled this version from source (229M and 20 minutes to build). However, it was consistent with the official package; these files were still missing. I'm not sure why they were present in the previous version, though…?

smirky · 2016-10-25 05:45:37

I confirm this problem and I actually narrowed it down to that particular package too. Anyway, my next step, as usual, was to check here so yeah, let's keep this thread moving

Salkay · 2016-10-25 05:53:57

FWIW I can confirm that you can just "steal" the `/usr/lib32/libQtWebKit.so*` files out of the older lib32-qt4 4.8.7-4, and copy them back into `/usr/lib32`, which allows Skype to work now. I still don't know why they'd be missing in the first place though, so hopefully someone knowledgeable can comment. Otherwise, I guess we should just file a bug.

merilius · 2016-10-25 10:40:08

Just installed skypeforlinux and ghetto skype. Both are basically web versions of skype ran within an "emulated browser". Skypeforlinux comes from Microsoft and is larger. Ghetto Skype seems to be a more recent web version, because it has more settings. Both have problems with adjusting microphone volume and video calls. Sharing screen is not possible. IMO the old/legacy skype v4.3 is still better than any of these and definitely smaller.

I wonder why do we use this proprietary binary blob with closed protocol and almost certainly with NSA spyware inside?

Until last lib32-qt4 upgrade skype works almost fine, at least I can call and chat to any version.
Yes, I know that it is crap, but there's people who still use it, and I have to speak to them.

r0b0t · 2016-10-25 11:55:01

I'm also having the same problem, for now I'm using https://web.skype.com/en/ with audio/video not working btw...

skunktrader · 2016-10-25 11:57:38

I guess what we need is the package lib32-qtwebkit

kalle · 2016-10-25 13:08:50

Hi

got skype-legacyto work.

Have virtual box running with kubuntu 14.04 as a guest. installed lib32-qt4 there and copied libQtWebKit.so.4 from there into ~/tmp/ at the arch host and soft-linked to /usr/lib32. Then tryed to start skype. When it comlained about missing libs I did the same as before for the missing libs (if they could not be installed from arch lib32 repos). In total I had to copy libQtWebKit, libgstapp, libgstaudio, libgstbase, libgstpbutils, libgsttag, libgstvideo, liborc and libxslt. However, the best is to start with libQtWebKit.so.4 and then let skype tell you what to copy next.

Finally skype-legacy started.

Is there any alternative for Skype? For Windows there is RazerComms (friends say that sound quality is better on this) but for Linux there is not single one, beside this "www stuff".

BTW - downagrading lib32-qt4 and lib32-sqlite fixed problem with

usr/lib32/skype/skype: error while loading shared libraries: libQtWebKit.so.4: cannot open shared object file: No such file or directory

also for me.

I have the same problem since upgrading those packages. Oh, well, maybe this is for the better. Ideally Skype will die tomorrow and some good ("family friendly") alternative will present itself. All that constant latency and poor sound quality....... I mean, the sound and low delay when using Mumble is so much better. I wish, I wish!

lib32-qt4 was just upgraded and it doesn't solve the problem.

Same issue again, but if I use the old libQtWebKit.so.4 file, magic happens

export LD_PRELOAD=/tmp/libQtWebKit.so.4 ; skype
ERROR: ld.so: object '/tmp/libQtWebKit.so.4' from LD_PRELOAD cannot be preloaded (wrong ELF class: ELFCLASS32): ignored.

Skype works, minus the ERROR message...

I don't have the time to create/follow a bug right now, but I think it's the expected workflow if we want to get this fixed...

Fixxer · 2016-10-25 20:08:02

Confirm. Package lib32-qt4 4.8.7-6 causes Skype's segfault.

R00KIE · 2016-10-25 20:46:26

Has anyone reported this on the bug tracker?

I'm also seeing this problem and right now I'm trying to recompile lib32-qt4 to see if the problem magically goes away (maybe some missing/optional dependency when building is missing).

Edit:
No dice, building fails at some point and I can't spend more time with this for now, downgrading it is.

I also get the "abort (core dumped)" error with lib32-qt4 4.8.7-6. Someone had already put up a bug report here. Clearly the new version isn't working for us. I tried to reopen the task, because the new fix isn't adequate, but it was rejected because "Library is no longer missing".

This had already been submitted and fixed, right? (See the rest of this thread.)

There's a new "abort (core dumped)" error with lib32-qt4 4.8.7-6. I'd file a bug for this, but I'm unsure how to verify that it's a lib32-qt4 bug, and not a skype bug.

Yes you are right, my mirror was a bit late so I installed now the lib32-qt4 update and it's as you say, core dumped.... Please I opened the first bug open this one
