Hi, I have changed opm-common to not build on 32bit architectures anymore in version 2023.04+ds-3 and requested removal of the binary packages in #1049463 [1].
Once the binaries are removed we should decrease the severity of this bug to allow migation of new versions to testing again. Best, Markus [1] https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=1049463
