This is not the live version of the release notes, which have been fixed: https://www.debian.org/releases/trixie/release-notes/ > On Trixie, readelf does not show the flags in most binaries, even > though according to the release notes, it should already be enabled in > Trixie. It is not enabled, that is exactly the purpose of this bug. > What is the difference between Ubuntu and Debian? Are the failing tests > specific to Debian? This is an upstream test that is failing, the issue has been reported here: https://sourceware.org/bugzilla/show_bug.cgi?id=31877 The author of the test explained it was a kernel or CPU bug, the latter being almost impossible as the issue is reproducible on different Intel and AMD CPUs. Ubuntu decided to just ignore the test. At the end, I spend some time debugging that last week-end, and I believe this is a buggy test. I posted a patch, which is under review, let's s see if I am right. If so, we can enable the feature for glibc 2.44 which should end up in Forky.
