I have been trying to update rust on Crux-3.8, but it always fails. This time, there was the 1.97.1-1 version available but the update failed again with the same error message (below):

is crux using rustup or do they have their own packaging system? can you explain in detail what command you are running and what's the expected output?
if this is a packaging issue. you should report to the crux package maintainer.
I am trying to update the whole Crux-3.8 system with "prt-get sysup", but after rust started failing I ran "prt-get update ", leaving rust aside from the rest of bunch of packages available to be update and the whole system updates perfectly well this way." Rust, however, shows an output of "crate" and "std" error. The installed version is 1.93.1-1, and there is already available the → 1.97.1-1 one.

this is most likely a downstream packager issue, not a problem in rust itself. better to report to the crux package maintainer.
I'm not familiar with the packaging system used by crux, are packages distributed in source code form and built locally? bootstrapping a rust compiler is slow and heavy, and should not be necessary for most users. do they have signed pre-built binaries in the repository?
note, it is recommended to use rustup to install rust toolchains for most users. typically you'll need to install rust from the system package manager only if you want to publish software written in rust to the distro's repositories.
If I am not mistaken, in the CRUX 3.8 distribution, the packages are distributed in source code format (through port collections) and are compiled and mounted locally on your machine. As far as I know, Crux officially provides pre-built binary packages for the compiler in the contrib collection, which completely avoids the need to bootstrap from source. I update the system by running "sudo ports -u", "prt-get diff", "sudo prt-get sysup" or "sudo prt-get update " if you prefer to update one by one. What is weird is that I have Crux on two other machines and there is no problem at all to update rust the way I related above.
