Your package src:rust-sequoia-net has been trying to migrate for 94 days [2] (yes, partially due to the freeze).
This package was uploaded to unstable by mistake, it should have been uploaded to experimental. Since it wasn't built on any architectures I decided the least disruptive thing to do during the freeze was to leave it alone.
Anyway, the freeze is over and sequoia-openpgp is updated, however there are still a couple of issues with this package. The first is that it depends on an old version of rust-base64, that one is trivially dealt with and indeed has already been fixed in experimental. The second however is it has a dependency on rust-trust-dns-client, this dependency is "optional" but "enabled by default". rust-trust-dns-client is currently only available on five out of 9 release architectures. This is due to dependencies on rust-rustls and rust-ring which are optional (and not enabled by default) at the cargo level but effectively mandatory with the current debian packaging. rust-rustls is architecture limited because of a dependency on rust-ring. The current version of rust-ring is architecture limited because it relies on assembler code for major parts of it's functionality. There has been some work upstream on making rust-ring more portable, but given the nature of the code, I would be reluctant to try and take it as a patch in Debian before it is included in an upstream release. So that IMO leaves the following options to move forward with this in the absense of a new upstream version of ring that is portable to all release architectures. 1. Simply patch out the feature in rust-sequoia-net, the reason I don't like this is because it's an enabled by default feature, downstream patches may suffer build failures with no obvious cause. 2. Implement https://salsa.debian.org/rust-team/debcargo/-/issues/49 and use it in the trust-dns packages, I did start doing some thinking about how I would implement it but I failed to find time when I was in the right frame of mind to do anything about it. 3. Manually patch the trust-dns packages to only expose the rustls/ring features on the architectures where they are supported, similar to what is currently done for the reqwest package. 4. Drop the rustls/ring support in the trust-dns packages completely. 5. Drop sequoia-net and it's reverse dependencies on architectures that do not support ring.
