Thanks. You may also edit the wiki. I've updated it now. > I tried that on two debian-12 systems.

My patch has an important omission. Thanks for testing. liblopsub1t64 should be marked "Multi-Arch: same". That annotation tells the package manager that this package can be installed multiple times for different architectures concurrently. On tracker.d.o, you see a note from the multiarch hinter about this. For that to work, the versions have to match up exactly, so you'll also need an amd64 build for testing this. > > You may also just upload to experimental.

Please keep in mind that NEW uploads must be binary (ftp master requirement) and that in order for your upload to migrate to testing, it must not be binary. Hence you usually need two uploads anyway. liblopsub may get away with a binNMU request as it does not build any Arch:all packages. Going through experimental for NEW uploads generally is recommended practice still. Helmut
