votes

I'm trying to install Rust on the Windows Subsystem for Linux (WSL) by running the following command which is provided officially here:

curl https://sh.rustup.rs -sSf | sh

I've installed Ubuntu from the Microsoft Store.

The problem is that the fails with 5 similar errors:

error: could not rename component file from '/home/thesdev/.rustup/tmp/glf5z1z643ehld0x_dir/bk' to '/home/thesdev/.rustup/toolchains/stable-x86_64-unknown-linux-gnu/share/man'

...

error: failed to install component: 'rust-docs-x86_64-unknown-linux-gnu', detected conflict: '"share/doc/rust/html"'

Screenshot of the installation process

Screenshot is from VS Code. Trying it in the Ubuntu application results in the same errors.

try strace and see what syscall fails – the8472
Please don't post your code as an image. I down voted because the same principle applies as Image of terminal output – Stargateur
@Stargateur I did it because it was lengthy. I included the more important parts of the output as text in the question though/ – thesdev
the is no problem, question can have a lot of character in it. Image can't be copied, mobile user and low connection user will prefer download 5ko than an image of 5Mo – Stargateur
@the8472 I'm not sure which part I should post but here is the last part of the output: ![wsl-error.png](postimg.cc/hJDpCq2j) – thesdev

Apparently, you need to close Visual Studio Code and run the command directly at the WSL prompt. The underlying issue is among the most-encountered WSL bugs:

I wouldn't be surprised if virus scanners could trigger this as well, not just Visual Studio Code.

It seems that adding sudo to the start of the command does the trick.

After several failed installations with the same error, I had to nuke my .rustup directory. I then ran the Rust installer with sudo. I recommend also temporarily turning off your antivirus protection, as that seems to cause issues.

The entire sequence of commands:

$ sudo rm -rf ./home/<your_username>/.rustup
$ curl 'https://sh.rustup.rs' -sSf > rustinstall.sh
$ sudo ./rustinstall.sh -y

Potential solution - disable your real-time antivirus protection during install

I had a very similar issue:

I read this thread - Installing rust-docs component on Windows 10 is very slow about an issue with the unpacking of the documentation on windows. They mention the anti-virus contributes to issues with speed.

I turned off my anti-virus real-time protection and ran the install script again, this time with no issues.

Rust is installed now. Great!

For anyone on WSL 2 try this:

export RUSTUP_IO_THREADS=1
curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh
