Hi, this error is relatively harmless, see the workaround in the crossgrader instructions
https://salsa.debian.org/crossgrading-team/debian-crossgrading/-/blob/master/INSTRUCTIONS.md#second-stage-the-rest-of-the-owl I just cross-graded my NAS this way from i386 to amd64 without a glitch (using --force-unavailable in the second stage after similar errors for linux-image-6.1.0-9-686:amd64 and linux-image-686:amd64). But the above file should be added to the package's docs and a hint to the file should be displayed when the program starts. Apparently README.md and INSTRUCTIONS.md were added in 0.0.4, but it was never uploaded. Cheers, Roderich
