rustup check does not list all installed versions #4013

Problem

rustup check does not list all installed rust versions in special situations

Steps

  1. We start at the point where only Rust stable is installed on the system (in my case Linux). It then looks like this
rtdietrich@pcx:~$ rustup check
stable-x86_64-unknown-linux-gnu - Up to date : 1.81.0 (eeb90cda1 2024-09-04)
rustup - Up to date : 1.27.1
rtdietrich@pcx:~$

  1. We now install version 1.80.0 on purpose, although 1.80.1 is already available at the time of writing and then try to list this installation with rustup check.

    
rtdietrich@pcx:~$ rustup install 1.80.0
info: syncing channel updates for '1.80.0-x86_64-unknown-linux-gnu'
info: latest update on 2024-07-25, rust version 1.80.0 (051478957 2024-07-21)

1.80.0-x86_64-unknown-linux-gnu installed - rustc 1.80.0 (051478957 2024-07-21)

info: checking for self-update rtdietrich@pcx:~$ rustup check stable-x86_64-unknown-linux-gnu - Up to date : 1.81.0 (eeb90cda1 2024-09-04) rustup - Up to date : 1.27.1 rtdietrich@pcx:~$ 


As can be seen, the `rust check` command incorrectly does not indicate that version 1.80.0 is installed on the system.

If you had entered `rustup install 1.80` instead of 1.80.0 under point 2, a subsequent `rustup check` would have listed all installed versions correctly

### Possible Solution(s)

_No response_

### Notes
Subsequently, I also discovered this and assume that this is not correct behavior

```terminal
rtdietrich@pcx:~$ rustup uninstall 1.80
info: no toolchain installed for '1.80-x86_64-unknown-linux-gnu'
info: toolchain '1.80-x86_64-unknown-linux-gnu' uninstalled
rtdietrich@pcx:~$ rustup uninstall 1.80.0
info: uninstalling toolchain '1.80.0-x86_64-unknown-linux-gnu'
info: toolchain '1.80.0-x86_64-unknown-linux-gnu' uninstalled
rtdietrich@pcx:~$

No response

@rtdietrich Thanks for filing this issue!

The rationale here is that 1.80.0 is pinned to a certain version, so it is not updatable. Thus, there's no point in checking updates for this channel. On the other hand, your 1.80 toolchain can be updated within the 1.80 series.

To check for all installed toolchains, use rustup show.

As for your concern on the message printed on rustup toolchain uninstall, see https://github.com/rust-lang/rustup/issues/3861.

Please feel free to tell us if you have further concerns.

I find everything you have written confusing, but as a newbie who is not really fit in the subject, I will leave it at that. Even though I think it will confuse a lot of users out there.

I would have liked rustup check to show version 1.80.0 and tell me that an update is available.

PS: Fortunately you have revised your post again and with the new explanation I understand a little more why things are like this: "pinned" brings light in my mind
