thank you, the patch w.r.t. the scope looks good to me.

can you also update the following:

1. echo "Support Ubuntu 18.xx, 20.xx" (here 24.xx should be also included)
2. the go download as of now doesn't take arch into account, when you run it on arm architecture (linux, arm64) then the script fails. Either terminate the script if arch is arm64 with a helpful error message or let's modify the script so that go download takes arch into account. To maintain the consistency of go version, we can consider using gotip https://github.com/golang/dl and this has to be done if go is already installed. If it's not installed then nothing needs to be done, download the latest stable go version.

@kranurag7 regarding the 2 point, we need gotip in arm64 case only?
Can you test this on an arm machine:

# install golang
echo "Installing golang binaries..."
arch=$(uname -m)
if [ "$arch" == "aarch64" ]; then
    arch="arm64"
elif [ "$arch" == "x86_64" ]; then
    arch="amd64"
else
    echo "Unsupported architecture: $arch"
    exit 1
fi

if command -v go &>/dev/null; then
    if [ "$arch" == "arm64" ]; then
        echo "Go is already installed on ARM architecture, setting up gotip..."
        go install golang.org/dl/gotip@latest
        gotip download
        echo "export PATH=\$PATH:\$HOME/sdk/gotip/bin" >> ~/.bashrc
        echo "export GOTOOLDIR=\$HOME/sdk/gotip/pkg/tool/linux_arm64" >> ~/.bashrc
        source ~/.bashrc
    else
        echo "Go is already installed."
    fi
else
    goBinary=$(curl -s https://go.dev/dl/ | grep "linux-$arch" | grep -Eo 'go[0-9.]+\.linux-'$arch'\.tar\.gz' | head -n 1)
    wget --quiet https://dl.google.com/go/$goBinary -O /tmp/build/$goBinary
    sudo tar -C /usr/local -xzf /tmp/build/$goBinary
fi

I have changed how goBinary gets computed as the earlier approach didn't work in case of arm64

Also, shall I make a new PR for the 2nd point or update here only?
