Hi Maintainer I've re-opened this bug since the problem persists, but have lowered the severity since the ceres-solver binaries were removed on arm64 and ppc64el.
I noticed the evaluation_callback_test started failing on i386 and is now skipped there [1]. Would it be reasonable to skip that test on arm64 and ppc64el as well? Regards Graham [1] https://salsa.debian.org/science-team/ceres-solver/-/commit/1aeb88db68902bf86c7f98d1755a2dd9ef127221
