Client: symbol lookup error on Ubuntu 16.04 with owncloud-client 2.2.0

[joysfera]

Expected behaviour

owncloud client should start

Actual behaviour

$ owncloud
owncloud: symbol lookup error: /usr/lib/x86_64-linux-gnu/libowncloudsync.so.0: undefined symbol: _ZN9QKeychain15ReadPasswordJob6setKeyERK7QString

Steps to reproduce

1. apt-get install owncloud-client
2. owncloud
3. 
   

   Client configuration

Client version: 2.2.0-1.1

Operating system: Ubuntu 16.04 64-bit

FYI, the Ubuntu 15.10 nightlies of 2.2.x worked OK but I thought I'd revert back to "stable" compiled precisely for my version of Ubuntu.

$ more /etc/apt/sources.list.d/owncloud.list
deb http://download.opensuse.org/repositories/isv:/ownCloud:/desktop/Ubuntu_16.04/ /

$ dpkg -l "*cloud*" | grep ^ii
ii  libowncloudsync0:amd64      2.2.0-1.1    amd64        the ownCloud sync library
ii  owncloud-client:amd64       2.2.0-1.1    amd64        The ownCloud sync client - github.com/owncloud/client
ii  owncloud-client-l10n        2.2.0-1.1    all          Internationalization files for ownCloud

$ ldd `which owncloud` | grep sync
    libowncloudsync.so.0 => /usr/lib/x86_64-linux-gnu/libowncloudsync.so.0 (0x00007f7b46d53000)
    libocsync.so.0 => /usr/lib/x86_64-linux-gnu/owncloud/libocsync.so.0 (0x00007f7b45938000)
    libxcb-sync.so.1 => /usr/lib/x86_64-linux-gnu/libxcb-sync.so.1 (0x00007f7b3c03f000)

[joysfera]

This seems to be caused by incorrect version of libqt5keychain0 - after uninstalling the nightly version there remains libqt5keychain0 version 0.6.2-11.1. If you then install a stable build it fails to run. You have to remove the libqt5keychain0 first and only then install the stable owncloud-client that in turn installs libqt5keychain0 version 0.5.0-1build1~gcc5.1 with which it works OK.
So this is basically a package issue - the libqt5keychain0 should have been uninstalled automatically and also the stable package should enforce installing the right version of libqt5keychain0 as apparently it doesn't work with a newer one.

[hefee]

The problem is that qtkeychain changed their ABI without bumping the SO Version.
A workaround is to recompile owncloudclient with libqtkeychain 0.6.2 and add this as dependency or add a break to the 0.6.X version to make sure that apt installs the correct version.

[danimo]

@hefee can you file this upstream?

[danimo]

Anyway, isv:ownCloud:desktop should have 0.6.2 as well. Fixing this now. Updated packages should be available in a few minutes.

[hefee]

@danimo as you may already noticed, - it is already filed upstream and linked to this thread: https://github.com/frankosterfeld/qtkeychain/issues/73

[danimo]

@hefee Shame on me. Didn't. Thanks!

Same issue after latest update on OpenSUSE LEAP 42.1:

owncloud: symbol lookup error: /usr/lib64/libowncloudsync.so.0: undefined symbol: _ZN9QKeychain3Job6setKeyERKT

This appeared after the last zypper update today. According to the rpm changelog, the package was updated on FR 13.5 by [email protected]:

Information for package owncloud-client:

[WalterFae]

Similar issue after latest upgrade on OpenSUSE 13.2:
"owncloud: symbol lookup error: /usr/lib64/libowncloudsync.so.0: undefined symbol: _ZN9QKeychain15ReadPasswordJob6setKeyERK7QString".
Worked again after downgrading libqt5keychain0 from 0.6.2-1.1-x86_64 (from isv:ownCloud:desktop) to 0.5.0-12.2-x86_64 (from KDE:Extra)

[danimo]

@WalterFae that is because 13.2 is currently not compiling: https://build.opensuse.org/package/live_build_log/isv:ownCloud:desktop/owncloud-client/openSUSE_13.2/i586. //cc @dragotin @jnweiger

[thommierother]

This workaround does not help on leap.
the symbol lookup error appears with libqtkeychain0 0.4-3.3 (OpenSUSE standard), 0.4-5.1 (KDE Extra) and 0.6.2-1.1 (isv: ownCloud)

[bulletxt]

I'm having same issue with Ubuntu 14.04:

owncloud: symbol lookup error: /usr/lib/x86_64-linux-gnu/libowncloudsync.so.0: undefined symbol: _ZN9QKeychain3Job6setKeyERK7QString

If it can help, doing ldd reports:
libowncloudsync.so.0 => /usr/lib/x86_64-linux-gnu/libowncloudsync.so.0 (0x00007ffa9fe1e000)
libocsync.so.0 => /usr/lib/x86_64-linux-gnu/owncloud/libocsync.so.0 (0x00007ffa9ecdb000)
libxcb-sync.so.1 => /usr/lib/x86_64-linux-gnu/libxcb-sync.so.1 (0x00007ffa9432d000)

However, libocsync package is not installed on my system and it's impossible to install as libowncloudsync0 package says it breaks libocsync0

Please find a solution, as of today I can't use owncloud client anymore!!

EDIT: please read post below, also my post was wrong for the simple reason that libocsync is directly provided from owncloud

[bulletxt]

I was having this issue because I had libqt5keychain0 0.5-9. I upgraded it to 0.6.2-1.1 (standard ubuntu update) and now it's finally working.

Thanks danimo irc user for suggestion

[volkerwysk]

Same as bulletxt here. I've upgraded from owncloud-client 2.1.1 to 2.2.0, and got the same "undefined symbol" error as the original poster. After upgrading libqt5keychain0 from version 0.5.0-1build1~gcc5.1 to 0.6.2-1.1, it worked again.

[newachu]

Same issue on Red Hat Enterprise Linux 6.8.
After installing latest stable 2.2.0, owncloud client won't start.
owncloud --logfile -
/opt/qt-4.8/bin/owncloud: symbol lookup error: /usr/lib64/libowncloudsync.so.0: undefined symbol: _ZN9QKeychain3Job6setKeyERK7QString

ldd /usr/lib64/libowncloudsync.so.0 shows
libqtkeychain.so.0 => /opt/qt-4.8/lib64/libqtkeychain.so.0 (0x00007f4bbcde4000)

[ckujau]

On this Debian/stable box, libqtkeychain0 would only be upgraded to 0.6.2 when apt-get is called with -t jessie-backports - although libqtkeychain0 is then fetched from the OC repo, not from the Debian backports repository. o_O

But now I have two packages: libqtkeychain0 (v0.6.2) and libqt5keychain0 (v0.4.0). After removing the latter, the original error is back:

$ owncloud 
owncloud: symbol lookup error: /usr/lib/x86_64-linux-gnu/libowncloudsync.so.0: undefined symbol: _ZN9QKeychain16WritePasswordJob6setKeyERK7QString

                 U _ZN9QKeychain16WritePasswordJob6setKeyERK7QString

[chrismyers81]

It looks like trying to upgrade libqtkeychain is not an option for me unfortunately; when I try to upgrade it, zypper says that the version I already have installed is 0.20131103-27.1 (0.6.2-2.1) from the ownCloud OBS repo, which is newer than the other versions that I can find out on OBS. I'm running oS 13.1 Evergreen 32-bit.

I thought that I'd just downgrade to the older version of the client then, but it doesn't exist on OBS anymore apparently :'(

[bjoernv]

chrismyers81, you need libqt5keychain0 from isv:ownCloud:desktop repository.

[thommierother]

The client packages for leap have been rebuild successfully (according to https://build.opensuse.org/project/monitor/isv:ownCloud:desktop). I just updated to version 2.2.0-5.1.xxxx.rpm including libqt5keychain0-0.6.2-1.1.x86_64.rpm and the symbol lookup errors are gone ;-)

[newachu]

RHEL6 still not fixed. Updated by yum:

[jnweiger]

@newachu I cannot reproduce your RHEL_6 issue:

wget -nv http://download.opensuse.org/repositories/isv:/ownCloud:/desktop/RHEL_6/isv:ownCloud:desktop.repo -O /etc/yum.repos.d/isv:ownCloud:desktop.repo
yum install owncloud-client

pulls in libowncloudsync0-2.2.0-5.1.x86_64 which has

rpm -q --requires libowncloudsync0 | grep keychain
libqtkeychain.so.0()(64bit)  
opt-libqtkeychain0 >= 0.6.2

So your opt-libqtkeychain0 should be upgraded to the correct version.

[jnweiger]

We did not increment the version number of libowncloudsync0 in this rebuild. Maybe you are stuck with the old one? It should be build release 5.1 ...

[chrismyers81]

Hmm, still no love for me :/

[newachu]

@jnweiger Thank you for the check. I tried to reinstall both libowncloudsync0 and opt-libqtkeychain0 with the following results:

Managed to fix the issue with full removal and reinstall:

yum install owncloud-client

Solved for RHEL6 :+1:

[chrismyers81]

I tried completely uninstalling and reinstalling from the repos, and when I chose to reinstall it's pulling libqtkeychain, not libqt5keychain : http://susepaste.org/5de15bdd

However, it looks like it's working now after doing a full uninstall-reinstall.

[jnweiger]

Happy to see that enforcing version 0.6.2 of qtkeychain/qt5keychain seems to solve the issue for everybody one way or the other. Please open new issues if more fixes are needed.

[ddrazyk]

On Fedora 24 you can workaround the issue by running dnf downgrade qtkeychain-qt5 qtkeychain. After that owncloud client runs fine.

[ionosphere]

Hi, under Ubuntu Mate 16.04 i have the same issue.

symbol lookup error: /usr/lib/x86_64-linux-gnu/libowncloudsync.so

Do you have any solution ?

[FriendFX]

This is what I did under Xubuntu 14.04 to get it working again:

sudo apt-get update
sudo apt-get remove owncloud-client
sudo apt-get autoremove
sudo apt-get install owncloud-client

Maybe it'll help someone.

[mtompkins]

I see this on Debian testing.
libqt5keychain0 is 0.6.2-1.1

Unfortunately this comment isn't valid as a general fix.

[sirlensen]

@FriendFX thx! Works! (Ubuntu 16.04)

[mtompkins]

@Cyb0org Pt2.

Full uninstall and reinstall after that package does indeed work. Thank you.

[ckujau]

On Debian/jessie, the owncloud-client would not work unless its version numbers were forced during the installation:

$ sudo apt-get -V install owncloud-client=2.2.0-2 libowncloudsync0=2.2.0-2 \
         owncloud-client-l10n=2.2.0-2 libowncloudsync0=2.2.0-2 \
         libqt5keychain0=0.6.2-1.1 libqtkeychain0=0.6.2-1.1

However, APT pinning may be a more elegant way to achieve the same:

$ cat /etc/apt/preferences.d/owncloud.pref 
Package: *
Pin: origin download.opensuse.org
Pin-Priority: 1000
$ sudo apt-get -V install owncloud-client
[...]
Get:1 http://download.opensuse.org/repositories/isv:/ownCloud:/desktop/Debian_8.0/  libqtkeychain0 0.6.2-1.1 [42.6 kB]
Get:2 http://download.opensuse.org/repositories/isv:/ownCloud:/desktop/Debian_8.0/  libowncloudsync0 2.2.0-2 [394 kB]
Get:3 http://download.opensuse.org/repositories/isv:/ownCloud:/desktop/Debian_8.0/  owncloud-client-l10n 2.2.0-2 [32.1 kB]
Get:4 http://download.opensuse.org/repositories/isv:/ownCloud:/desktop/Debian_8.0/  owncloud-client 2.2.0-2 [963 kB]

With that, owncloud-client is working again. The only oddity is the "%nil" in the version string in the "General" tab in the application:

[Florentin68]

Had same issue, my repository setting was still set on 15.10 while I have installed 16.04 a few weeks ago
Changing the repository to 16.04 and then reinstalling (thx to @FriendFX) worked well.

[EvilFreelancer]

@ckujau thank you a lot, your answer helped me!

[carboneater]

https://github.com/owncloud/client/issues/4829#issuecomment-221453981 fixed it for me (Debian/Sid).
Looks like Debian have an issue in their build of 2.2.0-2-dfsg. Pinning takes care of that though!

[jnweiger]

the trialing %nil will be fixed with 2.2.1 -- fixed the rules template today.
