Hi Maintainer You disabled arm64 for khmer and liboxli1 binary packages, but not for liboxli-dev. This prevented khmer from migrating [1] for the following reason:
liboxli-dev/arm64 unsatisfiable Depends: liboxli1 (= 2.0+dfsg-9) However, I suspect that the build failure on arm64 was transient (and it just built in Ubuntu), so I suggest re-enabling arm64 everywhere and uploading again. Regards Graham [1] https://qa.debian.org/excuses.php?package=khmer
