Can you help me install clang-14 on Ubuntu 18.04? I think I need a valid repo as apt-get install clang-14 does not work.

$ cat /etc/issue
Ubuntu 18.04 LTS \n \l

You neded ubuntu-toolchain-r ppa in bionic

sudo add-apt-repository ppa:ubuntu-toolchain-r/test

sudo apt update && sudo apt upgrade

wget https://apt.llvm.org/llvm.sh

chmod +x llvm.sh

sudo ./llvm.sh 14

And now are installed with clang-14 and clang++-14 .

clang-14 is not available for your release ... but available as of Ubuntu 22.04

So, upgrading to 22.04 is what you might want to consider.
