rustup update self should suggest rustup self update #3812
Description
Problem you are trying to solve
A new-ish user got confused about the command for updating rustup itself and tried rustup update self which gave this error:
error: error: invalid value 'self' for '[toolchain]...': invalid toolchain name: 'self'
For more information, try '--help'.
: invalid toolchain name: 'self'
Solution you'd like
Maybe something like:
note: use `rustup self update` to update rustup itself
Notes
I'm also not sure why the : invalid toolchain name: 'self' is repeated at the end. That seems redundant.

@ChrisDenton Thanks a lot! Should be an easy fix.

I'd like to give a shot

@rami3l, @djc I have something but before opening the PR I'm wondering how we want to show the message. Should we append, prepend or replace the message with the note?
rami3l commentedon May 8, 2024
@fbrv Following the example of rustc error messages, it seems to me that any "smart guess" lines should come after the original error message.
Please note that there could be a toolchain named self, so it's important to show the line on error exclusively.

Unfortunately, @fbrv just DM'd me and expressed their wish of backing out due to a personal incident. Thanks anyway for having offered to help!
