Go

Go builds the services, libraries and CLI. Any Go from 1.21 on works: it downloads the newer toolchain a repository asks for.

Install

Skip to Configure if this prints go1.21 or newer:

go version

The distribution's Go lags behind; install the official build:

GO_VERSION=$(curl -fsSL "https://go.dev/VERSION?m=text" | head -n 1)
GO_ARCH=$(uname -m | sed 's/x86_64/amd64/; s/aarch64/arm64/')
curl -fsSLo /tmp/go.tar.gz "https://go.dev/dl/$GO_VERSION.linux-$GO_ARCH.tar.gz"
sudo rm -rf /usr/local/go && sudo tar -C /usr/local -xzf /tmp/go.tar.gz
echo 'export PATH="$PATH:/usr/local/go/bin"' >> "$HOME/.$(basename "$SHELL")rc"
exec "$SHELL"

To upgrade, run the first four lines again.

Configure

Allow toolchain downloads

Skip if this prints auto:

go env GOTOOLCHAIN

Otherwise, your distribution turned downloads off. Turn them back on:

go env -w GOTOOLCHAIN=auto

Put Go programs on your PATH

The CLI installs into Go's program directory, ~/go/bin unless you moved it. Skip if echo "$PATH" lists it already.

GO_BIN="$(go env GOPATH)/bin"
printf 'export PATH="$PATH:%s"\n' "$GO_BIN" >> "$HOME/.$(basename "$SHELL")rc"
exec "$SHELL"

The rc stores the path itself, so a new shell starts no Go command. An rc line that calls go env GOPATH still works but starts Go in every new shell. Replace it with the one this block writes.
