Wrong version got installed for latest

[jankatins]

I used asdf update to install the latest version of rust and it got shown in asdf as 1.63. When calling cargo/rustc, these commands reported version 1.56. I did a asdf uninstall rust and reinstalled, leading to this session:

[20:16:25] λ  asdf install rust latest

  1.63.0-x86_64-unknown-linux-gnu installed - rustc 1.63.0 (4b91a6ea7 2022-08-08)


Rust is installed now. Great!

To get started you need Cargo's bin directory
(/home/jan/.asdf/installs/rust/1.63.0/bin) in your PATH
environment variable. This has not been done automatically.

To configure your current shell, run:
source "/home/jan/.asdf/installs/rust/1.63.0/env"


[20:17:11] λ  rustc --version
rustc 1.56.1 (59eed8a2a 2021-11-01)

[20:23:22] λ  ~/.asdf/installs/rust/1.63.0/bin/cargo --version
cargo 1.56.0 (4ed5d137b 2021-10-04)

In the end I had to do a rustup update to get the right versions:

[20:23:41] [1] ✗  rustup update
info: syncing channel updates for 'stable-x86_64-unknown-linux-gnu'
info: latest update on 2022-08-11, rust version 1.63.0 (4b91a6ea7 2022-08-08)
...
info: installing component 'rustfmt'
error: rustup is not installed at '/home/jan/.cargo'


[20:24:27] [1] ✗  cargo --version
cargo 1.63.0 (fd9c4297c 2022-07-01)

I've no clue what can influence what rustup is actually installing in the end, but this was surprising to me, I had expected that asdf rust versions are installed completely outside of any config I may locally have.

$HOME/.rustup/settings.toml contains (now, after rustup update!)

default_toolchain = "stable"
profile = "default"
version = "12"
