Bash completions don't work

[sealor]

Problem

The Bash completions don't work because they are not be sourced correctly.

Steps

Rustup expects Bash completions in ~/.rustup/toolchains/stable-x86_64-unknown-linux-gnu/etc/bash_completion.d/cargo:

$ rustup completions bash cargo
if command -v rustc >/dev/null 2>&1; then
        source "$(rustc --print sysroot)"/etc/bash_completion.d/cargo
fi

Unfortunately, the completions are not there:

$ ls -d "$(rustc --print sysroot)"/etc/bash_completion.d/cargo
ls: cannot access '/home/stefan/.rustup/toolchains/stable-x86_64-unknown-linux-gnu/etc/bash_completion.d/cargo': No such file or directory

But, the completions are here:

$ file "$(rustc --print sysroot)"/src/etc/bash_completion.d/cargo
/home/stefan/.rustup/toolchains/stable-x86_64-unknown-linux-gnu/src/etc/bash_completion.d/cargo: ASCII text

Note the /src/etc instead of just /etc.

Possible Solution(s)

The Bash completions should be placed in /etc/bash_completion.d/cargo instead of /src/etc/bash_completion.d/cargo.

Thanks for the report, and sorry for the inconvenience. This is a regression and planned to get a stable backport soon. See rust-lang/rustup#3407. Will keep this issue open till a new point release comes out (presumbly 1.71.1).

Fixed in 1.71.1 with rust-lang/rust#113579. Thanks you for reporting this!
