owncloud-client missing Debian_11 repo for building/installing from OBS repo

Trying to building owncloud-client for install for Raspberry Pi OS 64 bit (debian bullseye) following

apt update

E: The repository ‘http://download.opensuse.org/repositories/isv:/ownCloud:/desktop/Debian_11 Release’ does not have a Release file.
N: Updating from such a repository can’t be done securely, and is therefore disabled by default.
N: See apt-secure(8) manpage for repository creation and user configuration details.

Can you try with this one instead?

The build instructions in that appendix are outdated. More reports about success/failures welcome – this will help to update the build instructions.
