problem with the owncloud client after system update

The updated client fails to load:

owncloud: error while loading shared libraries: libqt5keychain.so.1: 

cannot open shared object file: No such file or directory

The client is installed from the obvious repo server: isv:ownCloud:desktop


The library in question is available as
(newer)

opt-libqt5keychain1-0.7.0-9.4.x86_64

from isv_ownCloud_desktop
and (older)

qtkeychain-qt5-0.7.0-1.el7.x86_64

from epel.

The CentOS 7 version of owncloud client is compiled against the epel version of qt5. This, it is necessary to drive the yum to install the epel version of the

libqt5keychain1

package:

yum remove opt-libqt5keychain1-0.7.0-9.4.x86_64
yum --disablerepo=isv_ownCloud_desktop install qtkeychain-qt5-0.7.0-1.el7.x86_64

yum install owncloud-client

Now, the complete owncloud client is installed from the epel  repository
