+I think I fixed this. I'm attaching the output of `git format-patch origin/master`.
+
+In an Arch Linux chroot with their [PKGBUILD](https://git.archlinux.org/svntogit/community.git/tree/trunk/PKGBUILD?h=packages/git-annex) (with a small modification to apply the patch), `haskell-http-client 0.5.3.3-1` and `http-conduit 2.2.3-5` both the build and the tests are successful.
+It's also successful in a Debian Sid chroot, where `sudo apt build-dep git-annex` gives me `libghc-http-client-dev 0.4.31.1-3+b2`, `libghc-http-conduit-dev 2.1.11-3+b2`.

+Subject: [PATCH] Remove http-conduit (<2.2.0) constraint
+
+Since https://github.com/aristidb/aws/issues/206 is resolved, this
+constraint is no longer necessary. However, http-conduit (>=2.2.0)
+requires http-client (>=0.5.0) which introduces some breaking changes.
+This commit also implements those changes depending on the version.
+Fixes: https://git-annex.branchable.com/bugs/Build_with_aws_head_fails/
