Please describe the problem.

All the new wonderful SHA3_* backends are gone from the Linux AMD64 build of 5.20150825-g7826f84. They exist in the i386 version (5.20150824-g8529cb2), though. It's probably compiled without Cryptonite support or something.

What steps will reproduce the problem?

Everything involving any of the SHA3_* backends result in an "unknown backend SHA3_*" error with the amd64 build (5.20150825-g7826f84). The i386 version (5.20150824-g8529cb2) works.

What version of git-annex are you using? On what operating system?

Newest official builds from downloads.kitenet.net . Debian GNU/Linux all the way.

Have you had any luck using git-annex before? (Sometimes we get tired of reading bug reports all day and a lil' positive end note does wonders)

Oh, yes. It rules. :) One of the most important programs I use because I have all my valuable stuff in it. My files have never been safer.

Yeah, debian unstable got too unstable and I had to move those autobuilders to testing, which didh't have the necessary library. They're back on unstable now, so done --Joey
