Following the tutorial “Hello, World! Rust CDK Quick Start”. Hello, World! Rust CDK Quick Start :: Internet Computer

It gives me the following error:

/rust_hello> dfx deploy

error: build failed
The build step failed for canister 'rrkah-fqaaa-aaaaa-aaaaq-cai' with an embedded error: The custom tool failed.

The solution in the following post does not work.-> error[E0463] when trying to run internet-identity

any ideas?

openSUSE TW, Rust and rustup from repos.

Solution:
Delete rust from the repositories, and install it from:

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