How to fix fatal: unknown option --no-optional-locks (git version too old) in Git

# Check Git version
git --version

# Expected output for a version that supports --no-optional-locks:
# git version 2.15.0 or higher

# Test if the flag is supported
git --no-optional-locks status
# If this fails with "unknown option", upgrade is needed

# Add the official Git PPA
sudo add-apt-repository ppa:git-core/ppa -y
sudo apt update

# Install or upgrade Git
sudo apt install git -y

# Verify the new version
git --version

# Install dependencies
sudo apt install software-properties-common -y

# Add the PPA manually

sudo apt install git -y

# For CentOS/RHEL 7+ - Use IUS repository
sudo yum install -y https://repo.ius.io/ius-release-el7.rpm
sudo yum install -y git236  # or latest available

# For Amazon Linux 2
sudo yum install -y git

# For Amazon Linux 2023
sudo dnf install -y git

# For RHEL 8/9 or CentOS Stream
sudo dnf install -y git

# Install build dependencies
sudo yum groupinstall -y "Development Tools"
sudo yum install -y curl-devel expat-devel gettext-devel openssl-devel zlib-devel perl-ExtUtils-MakeMaker

# Download and compile Git
cd /tmp
curl -LO https://github.com/git/git/archive/refs/tags/v2.43.0.tar.gz
tar -xzf v2.43.0.tar.gz
cd git-2.43.0
make prefix=/usr/local all
sudo make prefix=/usr/local install

# Verify installation
/usr/local/bin/git --version

# Update Xcode Command Line Tools (includes Git)
xcode-select --install

# Or install/update via Homebrew (recommended)
brew install git

# Ensure Homebrew's Git takes priority
echo 'export PATH="/opt/homebrew/bin:$PATH"' >> ~/.zshrc
source ~/.zshrc

# Verify
which git  # Should show /opt/homebrew/bin/git
git --version
