Gemini advice:

You're absolutely right! It seems that the clang-6.0 package isn't directly available in the default Ubuntu 22.04 repositories. Let's fix this and get your installation rolling.

Here's how to install clang-6.0 on Ubuntu 22.04:

1. Add the LLVM Repository: The LLVM project provides the necessary packages for Clang. Let's add their repository to our system:

   sudo wget -O - https://apt.llvm.org/llvm-snapshot.gpg.key | sudo apt-key add - 
   sudo add-apt-repository "deb http://apt.llvm.org/focal/ llvm-toolchain-focal-6.0 main"

2. Update Package Lists: Update the package lists to reflect the newly added repository.

   sudo apt-get update

3. Install clang-6.0: Now you should be able to install the specific version of Clang:

   sudo apt-get install -y clang-6.0

Additional Notes

• If you need other Clang-related tools, packages like clang-tools-6.0, lld-6.0, etc., might be useful. Install them similarly.
• You can adjust the -6.0 part to install a different minor version of Clang 6 if needed.

Rerun the Installation Command

Now that you have clang-6.0 installed, try running the backend compiler dependencies installation command again:

sudo apt-get install -y build-essential clang-6.0 libhdf5-serial-dev libzmq3-dev

This should now proceed without any issues.

@danindiana the instructions there are for Ubuntu 20.04.

For Ubuntu 22.04, official support is still in development, but these are the deps you will need:

apt update && apt install -y \
    build-essential \
    clang \
    curl \
    libboost-all-dev \
    libgl1-mesa-glx \
    libgoogle-glog-dev \
    libhdf5-serial-dev \
    libzmq3-dev \
    python-is-python3 \
    python3-pip \
    python3-venv \
    ruby \
    software-properties-common \
    wget

# Install libyaml
RUN wget http://mirrors.kernel.org/ubuntu/pool/main/y/yaml-cpp/libyaml-cpp-dev_0.6.2-4ubuntu1_amd64.deb
RUN wget http://mirrors.kernel.org/ubuntu/pool/main/y/yaml-cpp/libyaml-cpp0.6_0.6.2-4ubuntu1_amd64.deb
RUN dpkg -i libyaml-cpp-dev_0.6.2-4ubuntu1_amd64.deb libyaml-cpp0.6_0.6.2-4ubuntu1_amd64.deb
RUN rm libyaml-cpp-dev_0.6.2-4ubuntu1_amd64.deb libyaml-cpp0.6_0.6.2-4ubuntu1_amd64.deb

Yes, @milank94 you are correct. I noticed my mistake yesterday and re-installed correct Ubuntu (20.04) on the target server. Much better progress! Will close out.
