Package: libxfixes-dev Version: 1:5.0-4 Severity: normal Dear Maintainer, Multiarch install of libxcursor-dev is currently blocked because libxfixes-dev is not converted to support multiarch. I have checked that appart from libraries and pkgconfig files, every files are byte-for-byte identical across architectures so it should be safe to convert it to Multi-Arch: same. Thanks, Nicolas Le Cam
