I hope that this is the right place to ask this question…
I am using OpenSUSE Tumbleweed. The official client download page, Download Server Packages - ownCloud, directs to Install package isv:ownCloud:desktop / owncloud-client, and this, in turn, directs to a dysfunctional location containing the old owncloud-client-2.3.4-8626.2.x86_64.rpm, dated 21-Dec-2017, and also a few newer files like owncloud-client-dolphin-2.4.0-8911.12.x86_64.rpm, dated 14-Jan-2018.
First I thought that this was an oversight, and the correct client would eventually appear, but with every week passing I get a little bit more uneasy.
