The curve25519-dalek source package is currently being transfered to the
debian-rust team and debcargo-conf, and split into multiple source packages.
Because of this, the previous `all` package is replaced by architecture specific
packages.
I noticed the new librust-curve25519-dalek-derive-dev packages did not show up
in the archive yet, I suspect this is due to the previous `all` package. Please
remove that package, and if needed, trigger another build of the new source package.
Thank you,
