Rust crate opendal no longer builds on 32-bit architectures, as discussed in bug#1116574. The involved crate openssh-sftp-client
FWIW I see no good reason that openssh-sftp-client can't be supported on all architectures. i386 and armhf both support 64-bit atomics natively and on architectures where 64-bit atomics aren't natively available there is the portable-atomic crate. But I'm not going to revert a change made by the named maintainer of the openssh-sftp-client package.
it has been patched out by the mysteriously and DEB-3-lacking patch remove-bb8.
I'm not sure what is supposed to be mysterious about a patch called "remove-bb8" which removes the dependency on bb8 and the features that require it. I do agree though that it's counterproductive to keep the openssh and openssh-sftp-client dependencies around given that the only feature which uses them is patched out. In addition to the architecture support issue, keeping them around causes cargo to implicitly create features that don't exist upstream. So I'll go ahead and remove them along with the architecture-is-64-bit build-dependency.
