These downloads happn in download_liburing() in ceph.git/make-dist

We appear to have a target (https://codeload.github.com/axboe/liburing/tar.gz/refs/tags/liburing-0.7) and a fallback (https://git.kernel.dk/cgit/liburing/snapshot/liburing-0.7.tar.gz) for this dependency. There's hardcoded sha256 in make-dist to validate the download -- that check is what is failing here.

Complicating matters is that the two targets are not identical. The former untars into a directory tree with liburing-0.7 as the top level directory while the latter has liburing-liburing-0.7 as the top level. There's code in download_liburing to normalize that directory name, though the fallback will always fail the sha256 check.

The immediate cause here, therefore, is that https://github.com/axboe/liburing/archive/liburing-0.7.tar.gz seems to have changed from a sha256 of 8e2842cfe947f3a443af301bdd6d034455536c38a455c7a700d0c1ad165a7543 as specified in the make-dist to 2343e125d89600763ab277ef4699f1aa1d0d2076d60aba940de5737287bbc4b3.
