Rustup.rs cannot install toolchains with version <1.8.0


#1
info: syncing channel updates for '1.7.0-x86_64-unknown-linux-gnu'
error: could not download file from 'https://static.rust-lang.org/dist/channel-rust-1.7.0.toml.sha256' to '/home/malbarbo/.multirust/tmp/6t9nsq7whoilfy_1_file
info: caused by: http request returned an unsuccessful status code: 404

Can the support to install older versions be added?


#2

I’m curious, why do you need this? Upgrading the compiler has never introduced any issues for me.


#3

My guess would be if you had a library that you wanted to make sure runs on all versions of rust after a certain version


#4

It should be able to, but the functionality regressed recently.
