Installing Rust on Fedora: 1.98 and a domestic crates mirror

sudo dnf install cargo rust
rustc --version
cargo --version

rustc 1.98.1 (48a229cea 2026-09-01) (Fedora 1.98.1-1.fc45)
cargo 1.98.1 (797e8a9bc 2026-08-05) (Fedora 1.98.1-1.fc45)

cargo pulls rustc in as a dependency, but installing rust explicitly documents the intent. Both land in /usr/bin.

First project

cargo new hello
cd hello
cargo run

cargo new creates Cargo.toml and src/main.rs; cargo run compiles and executes.

cargo build --release
./target/release/hello

Pointing crates.io at a mirror

cargo fetches from index.crates.io by default, which is slow here:

mkdir -p ~/.cargo
cat > ~/.cargo/config.toml <<'EOF'
[source.crates-io]
replace-with = 'tuna'

[source.tuna]
registry = "sparse+https://mirrors.tuna.tsinghua.edu.cn/crates.io-index/"
EOF

The sparse+ prefix matters — it uses the HTTP index instead of cloning git, which is an order of magnitude faster.

Repository build versus rustup

This is the part that needs saying clearly:

You want	Use
build existing projects, CI	dnf install cargo rust, upgrades follow Fedora
a pinned release	rustup
nightly / beta toolchains	rustup (the repository carries stable only)
cross compilation, rustup target add	rustup
full isolation	the rust:1.98 container

The repository build has no rustup, so no toolchain switching and no rustup component add rustfmt clippy — those are separate Fedora packages.

With rustup:

curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh
source ~/.cargo/env
rustup toolchain install nightly
rustup default nightly

Domestic acceleration for rustup downloads:

export RUSTUP_DIST_SERVER=https://mirrors.tuna.tsinghua.edu.cn/rustup
export RUSTUP_UPDATE_ROOT=https://mirrors.tuna.tsinghua.edu.cn/rustup/rustup

Caution

rustup and the dnf packages conflict: both provide cargo/rustc. Before installing rustup, either sudo dnf remove cargo rust, or ensure ~/.cargo/bin precedes /usr/bin on PATH and confirm with which -a cargo.

Fedora’s add-ons are separate packages:

sudo dnf install rustfmt clippy

Common traps

Symptom	Cause
crate downloads slow or failing	no mirror configured, or a git index instead of sparse+
cargo: command not found	only rust installed (rustc alone); add cargo
rustup toolchain not taking effect	/usr/bin/cargo wins; check which -a cargo
rustfmt missing	it is a separate package on Fedora, not a rustup component
linking runs out of memory	use -j1 or add swap
