Description of problem: In some documentation to how to configure debian repository : http://download.gluster.org/pub/gluster/glusterfs/3.3/3.3.2/Debian/README http://download.gluster.org/pub/gluster/glusterfs/3.3/3.3.1/Debian/readme.txt http://download.gluster.org/pub/gluster/glusterfs/3.4/3.4.0/Debian/README Theirs configuration cause error when multi-arch ios enabled and this new arch are not provided in gluster repository. Actual results: If multi-arch is enabled for i386 (or any arch non managed in gluster repository) There is error when "apt-get update" : W: Failed to fetch http://download.gluster.org/pub/gluster/glusterfs/3.3/LATEST/Debian/apt/dists/wheezy/Release Unable to find expected entry 'main/binary-i386/Packages' in Release file (Wrong sources.list entry or malformed file) Expected results: no error How to fix : Only add [arch=amd64] after deb if you provide only amd64 binary. Exemple : echo "deb [arch=amd64] http://download.gluster.org/pub/gluster/glusterfs/3.4/3.4.1/Debian/apt wheezy main" > /etc/apt/sources.list.d/gluster.list
