I'm running on Ubuntu 24.04.02 LTS, after setting up my Nix pacakge environment i try running it with nix-shell and i get this error

~/jetstreamer$ nix-shell

It seems clang_16 has been removed from nix_pkgs

Update was able to get it to work, installing directly, so for Ubuntu, install llvm 16 using sudo apt install instead of

wget -qO- https://apt.llvm.org/llvm.sh | sudo bash -s -- 16

Full command for (Ubuntu 24.04.02 LTS)

sudo apt update
sudo apt install -y clang-16 llvm-16 llvm-16-dev libclang-16-dev \
  gcc-13 g++-13 zlib1g-dev libssl-dev libtool

# Set as default
sudo update-alternatives --install /usr/bin/clang clang /usr/bin/clang-16 100
sudo update-alternatives --install /usr/bin/clang++ clang++ /usr/bin/clang++-16 100

# Environment variables
export CC=clang-16
export CXX=clang++-16
