"directory does not exist" errors when rustup update

[liigo]

Problem

when rustup update, the following errors occur:

error: failure removing component 'rust-docs-x86_64-unknown-linux-gnu', directory does not exist: 'share/doc/rust/html'

after I mkdir these directories, another error occurs:

error: failure removing component 'rustc-x86_64-unknown-linux-gnu', directory does not exist: 'share/doc/rust/LICENSE-MIT'

after I creating an empty file (note: not directory) LICENSE-MIT, other errors occur:

error: failure removing component 'rustc-x86_64-unknown-linux-gnu', directory does not exist: 'share/doc/rust/README.md'
error: failure removing component 'rustc-x86_64-unknown-linux-gnu', directory does not exist: 'share/doc/rust/COPYRIGHT'
error: failure removing component 'rustc-x86_64-unknown-linux-gnu', directory does not exist: 'share/doc/rust/LICENSE-APACHE'

then I must create empty README.md, COPYRIGHT and LICENSE-APACHE files (note: they're not directory as the error says).

In the end, rustup update works OK.

Steps

1. manually delete "rust" directory inside ~\.rustup\toolchains\stable-x86_64-unknown-linux-gnu\share\doc
2. run rustup update

Note: I‘m really not realized in the first time that deleting this directory will stop rustup from runing. Contents in the directory (share/doc/rust) are all API documents (.html) and license & readme files, and I just want to save space of my SSD.

Possible Solution(s)

Ignore "file/directory not exist" errors when removing (old) components, only print a warning, and go on running.

Notes

No response

Rustup version

rustup 1.25.2 (17db695f1 2023-02-01)
info: This is the version for the rustup toolchain manager, not the rustc compiler.
info: The currently active `rustc` version is `rustc 1.67.1 (d5a82bbd2 2023-02-07)`

### Installed toolchains

```console
Default host: x86_64-unknown-linux-gnu
rustup home:  /home/liigo/.rustup

stable-x86_64-unknown-linux-gnu (default)
rustc 1.67.1 (d5a82bbd2 2023-02-07)

Did you manually delete items from the toolchain directory? If so, consider using rustup component remove instead. Rustup is a package manager, and it keeps track of what files are expected.

That said, we should be more robust about dealing with corrupt content on disk. (Edited - I see the steps now)

[rbtcollins]

I"m going to close this. The work for dealing with concurrent use and with corrupt contents (#2417) is sufficient I think

[rustdesk]

rm -rf ~/.rustup # this is a must
rm -rf ~/.cargo
curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh

works for me.
