Rustup: complete profile is an attractive nuisance

Steps

Operating system: Linux amd64

Use installer settings:

   default host triple: x86_64-unknown-linux-gnu
     default toolchain: nightly
               profile: complete
  modify PATH variable: no

Possible Solution(s)

Notes

[chhdao]

You may have interrupted the download.
If it's true.
You may need to clear your download cache.
Usually in ~/.rustup and ~/.cargo.

[mbuesch]

You may have interrupted the download.

No.

You may need to clear your download cache.
Usually in ~/.rustup and ~/.cargo.

No. This is a completely fresh start. rustup and cargo directories don't exist.

It only happens in complete profile. I guess two components provide the same file or something like that.
Please try to reproduce the problem.

[rbtcollins]

Don't use the complete profile. It is not intended for use.

[mbuesch]

Ah Ok.

So could we remove this user visible option?
It's pretty confusing to have a visible option that's not supposed to be used.

[kinnison]

I agree that it is confusing and I'll bring it up for discussion at our next dev-tools meeting. I'm considering hiding complete entirely as we've never really made it work properly.

[blesson3]

I'm using the default profile and I'm getting a similar error failed to install component: 'rust-docs-x86_64-unknown-linux-gnu', detected conflict: '"share/doc/rust/html/std/keyword.self.html"'. The non-native-host toolchain is required by cross, but I've boiled the issue down to the default profile used by rustup.

I even removed the ~/.rustup dir before installing to avoid other toolchain conflicts.

The install works using the minimal profile though, probably because it's not installing rust-docs component.

[rbtcollins]

@blesson3 no, you're hitting #2672

[kinnison]

For reference, from the dev-tools meeting, I was tasked with taking the discussion to the release team to see what they'd prefer to do between redefining the set of things in complete to something which can be guaranteed to install on stable toolchains, or to deprecating/removing it entirely.

In the meantime the dev-tools team, as a whole, was okay with the idea of hiding the complete profile (ie. removing it from documentation and CLI help) but leaving it possible to use. Perhaps increasing the warning that it is currently considered an unstable choice might be a good way to decrease people's expectations until we have a release team decision.

[rubin55]

Like @blesson3, I'm running into the exact same issue, but on Linux, Pop!_OS 20.04 (an Ubuntu variant). Note that this happens both with complete and default. The fact that complete could/should be hidden has nothing to do with this issue:

Note also that it's the exact same file that's conflicting (share/doc/rust/html/std/keyword.self.html). I can confirm that minimal works, because it does not install rust-docs-x86_64-unknown-linux-gnu.

[kinnison]

@rubin55 The rust-docs problem is not the same as the other problems on this. This implies you're installing a linux toolchain onto a non-linux host as that kind of error is more related to the fact that 1.50 and 1.51's documentation contains filenames which differ only by case which upsets Windows and mac filesystems in their default configuration

[eshikafe]

Please I am unable to install rust 1.51.0 on Ubuntu 20.10 (groovy).
What could be wrong?

Welcome to Rust!

This will download and install the official compiler for the Rust
programming language, and its package manager, Cargo.

Rustup metadata and toolchains will be installed into the Rustup
home directory, located at:

  /home/eshikafe/.rustup

This can be modified with the RUSTUP_HOME environment variable.

The Cargo home directory located at:

  /home/eshikafe/.cargo

This can be modified with the CARGO_HOME environment variable.

The cargo, rustc, rustup and other commands will be added to
Cargo's bin directory, located at:

  /home/eshikafe/.cargo/bin

This path will then be added to your PATH environment variable by
modifying the profile files located at:

  /home/eshikafe/.profile
  /home/eshikafe/.bashrc

You can uninstall at any time with rustup self uninstall and
these changes will be reverted.

Current installation options:
